Grammatical number

Basque declension has four grammatical numbers: indefinite, definite singular, definite plural, and definite close plural:

• The indefinite is used after the question words Zer? ("What?"), Zein? ("Which?") and Zenbat? ("How much? / How many?"), after indefinite numerals, such as zenbait ("some"), hainbat ("several"), honenbeste / horrenbeste / hainbeste ("so many / so much"), bezainbeste ("as much as / as many as"), and before asko, anitz (this one can go before nouns), ugari, pilo bat, mordo bat, after makina bat ("much, many, a lot, lots of, plenty of..."), before gutxi ("a few, little") and batzuk ("some"), and the numbers, if they do not refer to a defined amount: Zer etxe eraberritu duzu? ("What house[s] have you renewed?"), Zer etxe eraberritu dituzu? ("What houses have you renewed?"). Zein etxetan bizi zinen? ("In what house[s] were you living?"). Zenbat etxe dituzu? ("How many houses have you got?"). Lapurrak hainbat etxetan sartu dira ("The thieves have broken into a number of houses"). Lapurra hainbeste etxetan sartu da! ("The thief has broken into so many houses!").

A noun followed by an adjective or a demonstrative is in the absolutive case, and the last word in the phrase is declined: Etxea ("The house / House"). Etxe bat ("A house"). Etxe handi bat ("A big house"). Etxe handi batean ("In a big house"). Etxe handi hori ("That big house"). Etxe zuri handi horretan ("In that big white house").

If the amount is known, the plural grammatical numbers are used: Lapurrak bi etxetan sartu dira ("The thieves have broken in two houses" [indefinite: the houses are unknown to the speakers]). Lapurrak bizpahiru etxetan sartu dira ("The thieves have broken in two or three houses" [indefinite: the speakers does not know the exact amount of houses]). Lapurrak bi etxeetan sartu dira ("The thieves have broken in both houses" [definite plural: both are known to the speakers]). Lapurrak bi etxeotan sartu dira ("The thieves have broken in these two houses" [definite close plural: both are being shown by the speaker]).

The indefinite is also used in some idioms and set phrases: Egun on! ("Good day! / Good morning!"), On egin! ("Bon appetit!"), Etxez etxe ("From house to house"), Mezatara joan ("Go to the mass"), Etxe bila ibili ("To look for a house"), and as the root for compound words (etxe-galgarri, etxekalte, "Person or thing which brings loss to a home") or derivative words (etxeratu, "To go home / To send home"; etxekoi, "fond of home"; etxegile, "house-builder").

• The definite singular is used to designate a person or thing known or to present: Zer da eraikin hori? Nire etxea da. ("What is that building? It is my home"). Etxea nirea da ("The house is mine").

• The definite plural designates people or things known or present: Zer dira eraikin horiek? Nire etxeak dira. ("What are those buildings? They are my houses"). Etxeak nireak dira ("The houses are mine").

• The definite close plural refers to people or things which are in the vicinity of the speakers: Zer dira eraikinok? Nire etxeak dira. ("What are those buildings? They are my houses"). Etxeok nireak dira ("These houses are mine").

It is also used to include oneself in the group referred to: Nafarrak festazaleak dira ("The Navarrese like celebrations": the speaker is not a Navarrese). Nafarrok festazaleak gara ("We Navarrese like celebrations": the speaker is a Navarrese).

Verbs have four singular persons and three plural ones, as follows:

Singular:

• First person (the speaker): Euskalduna naiz ("I am Basque"). Testua idatzi dut ("I have written the text").
• Informal second person (the person the speaker is addressing to, i.e., an inferior, an animal, a child, a monologue with oneself): Euskalduna haiz ("Thou art Basque"). In some tenses, there are different verbs for a man or a woman: Testua idatzi duk ("Thou hast written the text [said to a man, a boy]", Testua idatzi dun ("Thou hast written the text [said to a woman, a girl]").
• Formal second person (the person the speaker is addressing to: a superior, somebody older, one's parents), the most frequent one: Euskalduna zara ("You [singular] are Basque"). Testua idatzi duzu ("You [sing.] have written the text").
• Third person (neither the speaker nor the listener): Handia da ("He / She / It is big"). Testua idatzi du ("He / She / It has written the text").

Plural:

• First person (the speaker and somebody else at least): Euskaldunak gara ("We are Basque"). Testua idatzi dugu ("We have written the text").
• Second person (the addressees): Euskaldunak zarete ("You [plural] are Basque [said to a group, either informally or formally]"). Testua idatzi duzue ("You [pl.] have written the text").
• Third person (more than one person outside the conversation): Handiak dira ("They are big"). Testua idatzi dute ("They have written the text").

English is typical of most world languages, in distinguishing only between singular and plural number. Singular corresponds to exactly one (or minus one), while plural applies to all other cases, including more and less than one or even 1.0.[6] The plural form of a noun is usually created by adding the suffix -(e)s. The pronouns have irregular plurals, as in "I" versus "we", because they are ancient and frequently used words going back to when English had a well developed system of declension. English verbs distinguish singular from plural number in the third person present tense ("He goes" versus "They go"). Old English also contained dual grammatical numbers; Modern English retains a few residual terms reflective of dual number (such as both and neither, as opposed to all and none respectively), but they are generally considered to no longer constitute a separate grammatical number.

The Finnish language has a plural form of almost every noun case (except the comitative, which is formally only plural).

• talo – house
• talot – houses
• taloissa – in the houses

However, when a number is used, or a word signifying a number (monta- many), the singular version of the partitive case is used.

• kolme taloa – three houses

and where no specific number is mentioned, the plural version of the partitive case is used

• taloja

and in the possessive (genitive)

• talon ovi (the house's door)
• talojen ovet (the houses' doors)

In modern Romance languages, nouns, adjectives and articles are declined according to number (singular or plural only). Verbs are conjugated for number as well as person. French treats zero as using the singular number, not the plural.

In its written form, French declines nouns for number (singular or plural). In speech, however, the majority of nouns (and adjectives) are not declined for number. The typical plural suffix, -s or -es, is silent, no longer indicating a change in pronunciation. Spoken number marking on the noun appears when liaison occurs.

• some plurals do differ from the singular in pronunciation; for example, masculine singulars in -al [al] sometimes form masculine plurals in -aux [o].
• Proper nouns are not pluralized, even in writing. (Les voitures, but Les Peugeot 404)

Normally, the article or determiner is the primary spoken indicator of number.

In Modern Hebrew, a Semitic language, most nouns have only singular and plural forms, such as ספר /ˈsefeʁ/ "book" and ספרים /sfaˈʁim/ "books", but some have distinct dual forms using a distinct dual suffix (largely nouns pertaining to numbers or time, such as אלפיים /alˈpajim/ "two thousand" and שבועיים /ʃvuˈajim/ "two weeks"), some use this dual suffix for their regular plurals (largely body parts that tend to come in pairs, such as עיניים /eiˈnajim/ "eyes", as well as some that do not, such as שיניים /ʃiˈnajim/ "teeth"), and some are inherently dual (such as מכנסיים /mixnaˈsajim/ "pants" and אופניים /ofaˈnajim/ "bicycle"). Adjectives, verbs, and pronouns agree with their subjects' or antecedents' numbers, but only have a two-way distinction between singular and plural; dual nouns entail plural adjectives, verbs, and pronouns.

The Mortlockese language of the Mortlock Islands uses a base 10 counting system. Pronouns, nouns and demonstratives are used exclusively in the singular and plural forms through the use of classifiers, suffixes and prefixes.[7] There are no other dual or trial grammatical forms in the Mortlockese language.[8] Different forms that can be used in the language include first person singular and plural words, second person singular words like "umwi," second person plural words like "aumi" used to refer to an outside group, and third person plural words.[9]

Modern Russian has a singular vs plural number system, but the declension of noun phrases containing numeral expressions follows complex rules. For example, "У меня (есть) одна книга/три книги/пять книг" ("I have one book-nom. sing./three book-gen. sing./five book-gen. plur."). See Dual number: Slavic languages for a discussion of number phrases in Russian and other Slavic languages.

The numeral "one" also has a plural form, used with pluralia tantum: одни джинсы/одни часы "one pair of jeans, one clock".[10] The same form is used with countable nouns in meaning "only": Кругом одни идиоты "There are only idiots around".

Swedish inflects nouns in singular and plural. The plural of the noun is usually obtained by adding a suffix, according to the noun's declension. The suffixes are as follows: -or in the 1st declension (e.g. flicka – flickor), -ar in the 2nd (e.g. bil – bilar), -er in the 3rd (e.g. katt – katter), -n in the 4th (e.g. äpple – äpplen) and no inflectional suffix is added for the nouns in the 5th declension (e.g. bord – bord). Verbs in Swedish do not distinguish singular from plural number, but adjectives do.

Wuvulu is an Austronesian language spoken on Wuvulu Island located in the Manus Province of Papua New Guinea. The language's numbering system is multiplicative construction, where each number is based on multiplying pre-existing numbers smaller than five. Wuvulu is most similar to most Oceanic languages, and their numbering system is representative of some systems found in the Marshall Islands. For example, the number two in Wuvulu is roa, and the number four in both Proto-Oceanic language and Wuvulu is fa. Therefore, the number eight in Wuvulu is constructed from two and four, resulting in fainaroa, translating into "four multiply two". Moreover, the Wuvulu language has different numerical systems for animate objects and inanimate objects. When referencing an inanimate object, the number seven is oloompalo; however, if it is an animate object, the word changes to oloromea.[11] The structure of a noun phrase looks like NP=(ART/DEMONSTRATIVE+)(NUMBER/QUANTIFIER+)(PREMODIFIERS+)NOUN(+MODIFER.) The number or quantifier appears in the middle of the noun phrase.[12]

In most languages with grammatical number, nouns, and sometimes other parts of speech, have two forms, the singular, for one instance of a concept, and the plural, for more than one instance. Usually, the singular is the unmarked form of a word, and the plural is obtained by inflecting the singular. This is the case in English: car/cars, box/boxes, man/men. There may be exceptional nouns whose plural form is identical to the singular form: one sheep/two sheep (which is not the same as nouns that have only one number).

Some languages differentiate between an unmarked form, the collective, which is indifferent in respect to number, and a marked form for single entities, called the singulative in this context. For example, in Welsh, moch ("pigs") is a basic form, whereas a suffix is added to form mochyn ("pig"). It is the collective form which is more basic, and it is used as an adjectival modifier, e.g. cig moch ("pig meat", "pork"). The collective form is therefore similar in many respects to an English mass noun like "rice", which in fact refers to a collection of items which are logically countable. However, English has no productive process of forming singulative nouns (just phrases such as "a grain of rice"). Therefore, English cannot be said to have a singulative number.

In other languages, singulatives can be regularly formed from collective nouns; e.g. Standard Arabic تفاح tuffāḥ "apple" → تفاحة tuffāḥah "(individual) apple", بقر baqar "cattle" → بقرة baqarah "(single) cow". In Russian, the suffix for forming singulative form is -ин- -in-; e.g. град grad "hail" → градина gradina "hailstone", лёд lyod "ice" → льдина l'dina "block of ice". In both Russian and Arabic, the singulative form always takes on the feminine gender. In Dutch, singulative forms of collective nouns are occasionally made by diminutives: snoep "sweets, candy" → snoepje "sweet, piece of candy". These singulatives can be pluralised like most other nouns: snoepjes "several sweets, pieces of candy".

The distinction between a "singular" number (one) and a "plural" number (more than one) found in English is not the only possible classification. Another one is "singular" (one), "dual" (two) and "plural" (more than two). Dual number existed in Proto-Indo-European, persisted in many ancient Indo-European languages that descended from it—Sanskrit, Ancient Greek, Gothic, Old Norse, and Old English for example—and can still be found in a few modern Indo-European languages such as Slovene.[13] Many more modern Indo-European languages show residual traces of the dual, as in the English distinctions both vs. all, either vs. any, neither vs. none, and so on. Former dual forms may broaden their meanings to become paucal forms: Norwegian både, for example, though cognate with English both, can be used with more than two things, as in X sparer både tid, penger, og arbeid, literally "X saves both time, money, and labour".

Many Semitic languages also have dual number. For instance, in Arabic all nouns can have singular, plural, or dual forms. For non-broken plurals, masculine plural nouns end with ون -ūn and feminine plural nouns end with ات -āt, whilst ان -ān, is added to the end of a noun to indicate that it is dual (even among nouns that have broken plurals).

Pronouns in Polynesian languages such as Tahitian exhibit the singular, dual, and plural numbers.

Palmerston Island English is perhaps unique in being a dialect of English with dual case pronouns, namely the first person inclusive 'yumi' and the third person 'himshe'.[14]

The dual may be restricted to certain morphological categories. For example, in North Saami, in possessive forms the possessor has three numbers (singular, dual, plural) whereas the noun possessed only has two (singular, plural).

The trial number denotes three items. The Oxford English Dictionary lists no word that specifically refers to three items. Several Austronesian languages mark the trial with pronouns and bound person agreement markers, including Larike[15] and the Oceanic languages of Mussau, Raga, and Anejom̃.[16] Lihir even has distinct pronouns for trial and paucal.[17] Trial pronouns have found their way into the Austronesian-influenced creole languages of Bislama[18] and Tok Pisin.[19] Trial pronouns can additionally be found in some Australian Aboriginal languages, such as Nunggubuyu[20] and Bininj Kunwok.[21]

The quadral number denotes four items together. Likewise, the quintal number denotes five items together. It is contested whether any natural language truly has or has had either.

Quadral and quintal forms of pronouns have been attested in Tok Pisin.[19][22] However, while these are grammatically possible, they are rare, and plural forms are almost always used in their place.

The quadral has been claimed to exist as a regular feature in the pronoun systems of several Austronesian languages, most notably Sursurunga,[23] Tangga,[24][25] and Marshallese.[26][27] These languages all have a five-way distinction in grammatical number, which has been claimed to be singular/dual/trial/quadral/plural. However, it has also been noted that in all three cases, it is also possible to use the supposed quadral to refer to more than four. In Sursurunga, the "trial" actually refers to groups of three or four, or nuclear families of any size; the "quadral" is used for groups of four or more, or for two or more dyads. The Sursurunga grammatical number distinction has thus instead been categorized as singular/dual/paucal/greater paucal/plural. Tangga, as a closely related language, seems similar, although data is sparser. For Marshallese, there is consensus that the language has a true trial indicating exactly three. While its apparent quadral can mean exactly four, it also has an alternate rhetorical use in speeches to larger groups in order to impart a sense of individual intimacy.[28]

However, there is not consensus this means that Marshallese does not truly have a quadral. Similar rhetorical uses are found in other languages: in Djambarrpuyngu, a singular/dual/plural language, the dual can also be used rhetorically for speeches to crowds,[29] but it is still classified as a dual.[30] The same is true of the dual in Paamese, a singular/dual/paucal/plural language.[31] The most recent and comprehensive work on Marshallese grammar still refers to it as having a quadral.[27]

Quadral pronoun forms have also been more recently claimed by Robert Blust to exist in some Kenyah languages, specifically the highland Lepoʼ Sawa dialect spoken in Long Anap.[32] Corroborating data is lacking, and an investigation into the lowland Lebo’ Vo’ dialect has revealed a singular/dual/trial/paucal/plural system instead.[33]

In some languages with a singular/dual/trial/plural pronoun system, the plural forms are etymologically related to the number four. This has led to suggestions or assertions that historically a true quadral did exist, but it has since morphed into a plural form. Possible cited examples include Tolai,[34] Konomala, Patpatar, Kandas, Siar,[35] Tabar, Label, Gao, Kwamera,[24] Kawe, Wauyai, Matbat,[36] Larike,[37] Wamesa,[38] Ambai,[39] Loniu,[40] and Badeng.[33] Such shifts would not be unparalleled; the Mokilese plural pronouns are former trials, and the Icelandic plural pronouns are former duals.[41]

Many sign languages have been explicitly described as having quadral pronoun forms, including New Zealand Sign Language,[42] Brazilian Sign Language,[43] Hong Kong Sign Language,[44] Russian Sign Language,[45] Estonian Sign Language,[46] Jamaican Sign Language,[47] and Konchri Sain.[48] Other sign languages have been described as having both quadral and quintal pronoun forms, including American Sign Language,[49][50] British Sign Language,[51] and Levantine Arabic Sign Language.[52] According to linguist Sam Lutalo-Kiingi's 2014 thesis on Ugandan Sign Language, the language's pronouns have quadral forms, quintal forms, and rarely even forms for six people.[53]

Such categorization of sign language pronouns has been contested. Linguist Susan McBurney has contended that American Sign Language has a true dual, but that the trial, quadral, and quintal should instead be classified as numeral incorporation rather than grammatical number. This is motivated by the dual marker handshape being distinct from the handshape for the numeral two, in contrast to higher number markers; the ability to also incorporate these numerals into other words, including those for times and amounts; and the use of markers higher than the dual not being obligatory, with replacement by the plural being acceptable. There was not enough available data for McBurney to argue whether or not these reasons equally applied to other sign languages.[54] Linguist Raquel Veiga Busto has argued they do not equally apply to Catalan Sign Language, and has applied the terms quadral and quintal to the language's pronouns for convenience without taking an official stance as to whether they are grammatical number or numeral incorporation.[55] A third model is to categorize the apparent trial/quadral/quintal forms as "cardinal plurals", or forms of the grammatical plural number where the number of people is specified.[56]

Other authors have treated these concepts as equivalent, referring to pronoun numeral incorporation while still applying the terms quadral and quintal.[47][53] This would have implications for the existence of grammatical number in sign languages beyond quintal, since some American Sign Language speakers have been observed incorporating numerals up to nine into inclusive pronouns,[57] and Israeli Sign Language has the grammatical ability to incorporate numerals up to ten into pronouns.[58] Pronominal numeral incorporation has also apparently been documented in spoken languages: in addition to having singular, dual, trial, and plural forms, the pronouns of Mongondow and Lolak have been described as having "count forms", or forms that allow for arbitrarily high numeral incorporation, attested at least up to 12.[59] Similarly, Hoava has been described as having a quadral form due to pronoun forms with added numerals,[60] although this has been contested.[61]

The paucal number represents 'a few', a small inexactly numbered group of referents. It can be found in Hopi, Warlpiri, Lower Sepik-Ramu languages,[62] some Oceanic languages including Fijian,[63] Motuna,[64] Serbo-Croatian,[65] and in Arabic for some nouns. The paucal number has also been documented in some Cushitic languages of Ethiopia, including Baiso, which marks singular, paucal, plural.[66] When paucal number is used in Arabic, it generally refers to ten or fewer instances.

Of the Indo-European languages, Kurmanji (also known as Northern Kurdish) is one of the few known languages with paucal number. For instance: "car-IN-an" (sometimes), cf. "gelek car-an" (many times) and "car" (time). Another example is "sêv-IN-an" (some apples), "sêvan" (the apples), "sêv" (apple). It can be applied to basically all nouns. In Russian, the genitive singular is also applied to two, three or four items (2, 3, 4 ка́мня – stones, gen. sg.; but 5...20 камне́й – stones, gen. pl.), making it effectively paucal (cf. э́тот ка́мень – this stone, nom. sg.; э́ти ка́мни – these stones, nom. pl.). Polish functions similarly: 'one dog' is jeden pies', while (2, 3, 4 psy – dogs, pl.; but 5+ psów – dogs, gen. pl.). Slovene has one more distinction. With its use of dual ('one dog' is en pes, 'two dogs' is dva psa), paucal is only used for counting 3 and 4 (3, 4 psi – dogs, pl.; but 5+ psov – dogs, gen.pl.).

Distributive plural number is for many instances viewed as independent individuals (for example, in Navajo).

Superplural is a grammatical number referring to "a lot of items", "heaps of items". This "massive plural" is in contrast to the normal "plural". For example, the Australian Aboriginal Barngarla language has four grammatical numbers: singular, dual, plural and superplural.[67]^{: 227–228} For instance:

• wárraidya "emu" (singular)
• wárraidyalbili "two emus" (dual)
• wárraidyarri "emus" (plural)
• wárraidyailyarranha "a lot of emus", "heaps of emus" (superplural)[67]^: 228

Plurality is sometimes marked by a specialized number particle (or number word). This is frequent in Australian and Austronesian languages. An example from Tagalog is the word mga [mɐˈŋa]: compare bahay "house" with mga bahay "houses". In Kapampangan, certain nouns optionally denote plurality by secondary stress: ing laláki "man" and ing babái "woman" become ding láláki "men" and ding bábái "women".

In Sanskrit and some other languages, number and case are fused categories and there is concord for number between a noun and its predicator. Some languages however (for example, Assamese) lack this feature.

Languages that show number inflection for a large enough corpus of nouns or allow them to combine directly with singular and plural numerals can be described as non-classifier languages. On the other hand, there are languages that obligatorily require a counter word or the so-called classifier for all nouns. For example, the category of number in Assamese is fused with the category of classifier, which always carries a definite/indefinite reading. The singularity or plurality of the noun is determined by the addition of the classifier suffix either to the noun or to the numeral. Number system in Assamese is either realized as numeral or as nominal inflection, but not both. Numerals [ek] 'one' and [dui] 'two', can be realized as both free morpheme and clitics. When used with classifiers, these two numerals are cliticised to the classifiers.

Pingelapese is a Micronesian language spoken on the Pingelap atoll and on two of the eastern Caroline Islands, called the high island of Pohnpei. In Pingelapese, the meaning, use, or shape of an object can be expressed through the use of numerical classifiers. These classifiers combine a noun and a number that together can give more details about the object. There are at least five sets of numerical classifiers in Pingelapese. Each classifier has a numeral part and a classifier part that corresponds to the noun it is describing. The classifier follows the noun in a phrase. There is a separate set of numerical classifiers that is used when the object is not specified. Examples of this is the names of the days of the week.[69]

In many languages, such as English, number is obligatorily expressed in every grammatical context. Some limit number expression to certain classes of nouns, such as animates or referentially prominent nouns (as with proximate forms in most Algonquian languages, opposed to referentially less prominent obviative forms). In others, such as Chinese and Japanese, number marking is not consistently applied to most nouns unless a distinction is needed or already present.

A very common situation is for plural number to not be marked if there is any other overt indication of number, as for example in Hungarian: virág "flower"; virágok "flowers"; hat virág "six flowers".

Many languages, such as Chinese, Korean, Japanese and Malay (including Indonesian and Malaysian), particularly spoken in Southeast and East Asia, have optional number marking. In such cases, an unmarked noun is neither singular nor plural, but rather ambiguous as to number. This is called transnumeral or sometimes general number, abbreviated TRN. In many such languages, number tends to be marked for definite and highly animate referents, most notably first-person pronouns.

The languages of the Tanoan family have three numbers – singular, dual, and plural – and exhibit an unusual system of marking number, called inverse number (or number toggling). In this scheme, every countable noun has what might be called its "inherent" or "expected" numbers, and is unmarked for these. When a noun appears in an "inverse" (atypical) number, it is inflected to mark this. For example, in Jemez, where nouns take the ending -sh to denote an inverse number, there are four noun classes which inflect for number as follows:

As can be seen, class-I nouns are inherently singular, class-II nouns are inherently plural, class-III nouns are inherently singular or plural. Class-IV nouns cannot be counted and are never marked with -sh.*[70]

A similar system is seen in Kiowa (Kiowa is distantly related to Tanoan languages like Jemez):

(See also Taos language: Number inflection for a description of inverse number suffixes in another Tanoan language.)

In many languages, verbs are conjugated according to number. Using French as an example, one says je vois (I see), but nous voyons (we see). The verb voir (to see) changes from vois in the first person singular to voyons in the plural. In everyday English, this often happens in the third person (she sees, they see), but not in other grammatical persons, except with the verb to be.

Adjectives often agree with the number of the noun they modify. For example, in French, one says un grand arbre [œ̃ ɡʁɑ̃t aʁbʁ] "a tall tree", but deux grands arbres [dø ɡʁɑ̃ zaʁbʁ] "two tall trees". The singular adjective grand becomes grands in the plural, unlike English "tall", which remains unchanged.

Other determiners may agree with number. In English, the demonstratives "this", "that" change to "these", "those" in the plural, and the indefinite article "a", "an" is either omitted or changes to "some". In French and German, the definite articles have gender distinctions in the singular but not the plural. In Italian, Spanish and Portuguese, both definite and indefinite articles are inflected for gender and number, e.g. Portuguese o, a "the" (singular, masc./fem.), os, as "the" (plural, masc./fem.); um, uma "a(n)" (singular, masc./fem.), uns, umas "some" (plural, masc./fem.), dois, duas "two" (plural, masc./fem.),

In the Finnish sentence Yöt ovat pimeitä "Nights are dark", each word referring to the plural noun yöt "nights" ("night" = yö) is pluralized (night-PL is-PL dark-PL-partitive).

Sometimes, grammatical number will not represent the actual quantity, a form-meaning mismatch. For example, in Ancient Greek neuter plurals took a singular verb.[71] The plural form of a pronoun may also be applied to a single individual as a sign of importance, respect or generality, as in the pluralis majestatis, the T–V distinction, and the generic "you", found in many languages, or, in English, when using the singular "they" for gender-neutrality.

In Arabic, the plural of a non-human noun (one that refers to an animal or to an inanimate entity regardless of whether the noun is grammatically masculine or feminine in the singular) is treated as feminine singular—this is called the inanimate plural. For example:

رجل جميل (rajul jamīl) 'beautiful/handsome man': rajul (man) is masculine singular, so it takes the masculine singular adjective jamīl.

بيت جميل (bayt jamīl) 'beautiful house': bayt (house) is masculine singular, so it takes the masculine singular jamīl.

كلب جميل (kalb jamīl) 'beautiful dog': kalb (dog) is masculine singular, so it takes the masculine singular jamīl.

بنت جميلة (bint jamīlah) 'beautiful girl': bint is feminine singular, so it takes the feminine singular jamīlah.

سيارة جميلة (sayyārah jamīlah) 'beautiful car': sayyārah is feminine singular, so it takes the feminine singular jamīlah.

رجال جميلون (rijāl jamīlūn) 'beautiful/handsome men': rijāl (men) is masculine plural, so it takes the masculine plural jamīlūn.

بنات جميلات (banāt jamīlāt) 'beautiful girls': banāt is feminine plural, so it takes the feminine plural jamīlāt.

but

بيوت جميلة (buyūt jamīlah) 'beautiful houses': buyūt (houses) is non-human plural, and so takes the inanimate plural (feminine singular) jamīlah.

سيارات جميلة (sayyārāt jamīlah) 'beautiful cars': sayyārāt is non-human plural, and so takes the inanimate plural jamīlah.

كلاب جميلة (kilāb jamīlah) 'beautiful dogs': kilāb is non-human plural, and so takes the inanimate plural jamīlah.

A collective noun is a word that designates a group of objects or beings regarded as a whole, such as "flock", "team", or "corporation". Although many languages treat collective nouns as singular, in others they may be interpreted as plural. In British English, phrases such as the committee are meeting are common (the so-called agreement in sensu "in meaning"; with the meaning of a noun, rather than with its form, see constructio ad sensum). The use of this type of construction varies with dialect and level of formality.

In some cases, the number marking on a verb with a collective subject may express the degree of collectivity of action:

• The committee are discussing the matter (the individual members are discussing the matter), but the committee has decided on the matter (the committee has acted as an indivisible body).
• The crowd is tearing down the fences (a crowd is doing something as a unit), but the crowd are cheering wildly (many individual members of the crowd are doing the same thing independently of each other).
