Sanskrit compound

An endocentric compound, usually called determinative, is where the compound is essentially the sum of its parts, the meaning being an extension of one of the parts:

• blackbird → a type of black bird[lower-alpha 3]
• White House → the official residence of the US president[lower-alpha 4][8]
• siṃha·purás → lion-city (Singapore)

An exocentric compound refers to something outside the components:

• redhead → someone with red hair[lower-alpha 5]
• pickpocket → someone who picks someone else's pockets[lower-alpha 6][7]
• 'bahu·vrīhi' → lit. 'much-rice', i.e., possessing much rice: an indication of wealth

Indeed, this term 'bahuvrihi' is used both in Sanskrit and standard Indo-European linguistics to denote this type of compound.[9]

Sanskrit expands on these to provide several further distinctions as below:

A tatpuruṣa is an endocentric compound composed of two elements, wherein the first one, named the attributive, determines the second one.[11][12]

Based on the grammatical nature of the attributive member, six varieties of tatpuruṣa compounds are identified as seen in the classification above. A further distinction is also made based on whether the attributive is in the nominative or an oblique[lower-alpha 8] case.[10][11][lower-alpha 9]

The first member here is an attributive in an oblique relationship with the second, and are therefore termed dependent determinatives.[11][13]

In a karmadhāraya-tatpuruṣa compound, the first element qualifies the second one adjectively when the latter is a noun. When the second member is an adjective, the qualification is adverbial. Other parts of speech besides adjectives and adverbs may be used to obtain the adjective or adverbial qualification.[14][15]

In essence dvigu can refer to several compound types where the first element is a numeral.[lower-alpha 10] Dvigu-tatpuruṣa compounds are a special subcategory of karmadhārayas.[16][17]

dvigu compounds of bahuvrīhi type are noted below.

In a nañ-tatpuruṣa compound, the first element is a privative, a negator: a-, an- or na-, just like the English un-, Latin-derived in-, non- or Greek-derived a-, an-.[18][19]

These are composed of a second member that occurs only in a compound and cannot stand on its own.[lower-alpha 11] These are either roots or verbal derivatives from them.[20][21]

In an aluk-tatpuruṣa compound, in contrast to the standard pattern of being in stem form, the first element takes a case form as if in a sentence:[22]

These consist of two or more noun stems connected with "and" (copulative or co-ordinative). There are mainly three kinds of dvandva pair constructions in Sanskrit:[27]

The result of itaretara-dvandva[lower-alpha 12] is an enumerative word, the meaning of which refers to all its constituent members. The resultant compound word is in the dual or plural number and takes the gender of the final member in the compound construction. Examples:[28][29]

Words may be organised in a compound to form a metonym, and sometimes the words may comprise all the constituent parts of the whole. The resultant bears a collective sense and is always singular and neutral.[30]

According to some grammarians, there is a third kind of dvandva, called ekaśeṣa-dvandva,[lower-alpha 13] where only one stem remains in the compound of multiple words.[31]

While not strictly copulative, this is a compound consisting of the same word repeated with the first occurrence accented.

Āmreḍita compounds are used to express repetitiveness; for example, from dív- (day) we obtain divé-dive ('day after day', daily) and from devá- (god) we obtain deváṃ-devam or devó-devas ('deity after deity').[32]

Bahuvrīhi[lower-alpha 15] is an exocentric compound consisting of a noun preceded by a grammatical modifier which, taken together, functions as a single nominalised adjective.

A bahuvrīhi compound can often be translated by "possessing..." or "-ed"; for example, "possessing much rice" or "much-riced". In English, examples of bahuvrīhi would be "lowlife" and "blockhead" (they respectively denote 'one whose life is low' and 'one whose head resembles a block'), or the English surname Longbottom ('one who lives in a long "botham" [valley]').

The second element could essentially have been a noun, which within such a compound, can take on adjective declensions with the compound used adjectivally. Endocentric compounds can thus be transformed into possessives, normally accompanied, and explicitly recognized in the older language, by a change in accentuation:[33][34]

• indra·śatrú-, 'Indra's killer' ⇒ índra·śatru-, 'having Indra as killer'[lower-alpha 16]
• bṛhad·ratha-, 'a great chariot' ⇒ bṛhád·ratha-, 'having great chariots'
• sūrya·tejás-, 'sun's brightness' ⇒ sū́rya·tejas-, 'possessing the brightness of the sun'

A few typical examples of such compounds:[36]

When the first element of a bahuvrīhi is a numeral, the compound is called dvigu.[lower-alpha 18] An English example would be a halfwit ('one who has half of their mind').

A few typical examples of such compounds:[38]

Avyayībhāvas ('indeclinable') are adverbial compounds composed of an indeclinable element (an adverb, etc.) and a noun, together expressing an adverb or another indeclinable (avyaya) element.[39][40]
