Past tense

In English, the past tense (or preterite) is one of the inflected forms of a verb. The past tense of regular verbs is made by adding -d or -ed to the base form of the verb, while those of irregular verbs are formed in various ways (such as see→saw, go→went, be→was/were). With regular and some irregular verbs, the past tense form also serves as a past participle. For full details of past tense formation, see English verbs.

Past events are often referred to using the present perfect construction, as in I have finished (also known as present in past). However this is not regarded as an instance of the past tense; instead it is viewed as a combination of present tense with perfect aspect, specifying a present state that results from past action.[4] (It can be made into a past tense form by replacing the auxiliary have with had; see below.)

Various multi-word constructions exist for combining past tense with progressive (continuous) aspect, which denotes ongoing action; with perfect aspect; and with progressive and perfect aspects together. These and other common past tense constructions are listed below.

• The simple past consists of just the past tense (preterite) form of the verb (he walked, they flew, etc.), although when it is negated, emphasized or inverted it is sometimes necessary to unfuse the verb, using a periphrastic construction with did (as in did he walk? etc.) – see do-support. The simple past is used for describing single occurrences or habitual occurrences in the past, and sometimes for states existing in the past with no connection to the present (or where such connection is irrelevant), and sometimes for states and sensual perceptions existing in the past.
• The past progressive (past continuous) is formed using the simple past of be (was or were) with present participle (sometimes referred to as the -ing form) of the main verb: He was going. This form indicates that an action was ongoing at the past time under consideration, often interrupted by another past action (as in I was having a shower when you called).
• The past perfect combines had (the simple past of have) with the past participle of the main verb: We had shouted. This denotes that an action occurred before a specified time in the past, and therefore has similar function to the pluperfect found in some languages.
• The past perfect progressive (sometimes referred to as the past perfect continuous) combines had (the simple past of have) with been (the past participle of be) and the present participle of the main verb: You had been waiting. It is used to refer to an ongoing action that continued up to the past time of reference.
• The expression used to (with the infinitive of the main verb) denotes a past habitual situation (I used to play football when I was young), although with a stative verb it can just indicate that a state was continuously in effect (I used to belong to that club). It is often used to emphasize that something happened a long time ago and is no longer the case. Another way of referring to past habitual action is to use would, as in As a child I would play the piano every day, although this auxiliary has other uses as well. For further details see English modal verbs.

For details of the usage of the various constructions used to refer to the past, see Uses of English verb forms. The past tense is also used in referring to some hypothetical situations, not necessarily connected with past time, as in if I tried or I wish I knew. (For the possible use of were in place of was in such instances, see English subjunctive.)

German uses three forms for the past tense.

• The preterite (Präteritum) (called the "imperfect" in older grammar books, but this, a borrowing from Latin terminology, ill describes it.)
• The perfect (Perfekt)
• The past perfect (Plusquamperfekt)

In southern Germany, Austria and Switzerland, the preterite is mostly used solely in writing, for example in stories. Use in speech is regarded as snobbish and thus very uncommon. South German dialects, such as the Bavarian dialect, as well as Yiddish and Swiss German, have no preterite (with the exception of sein and wollen), but only perfect constructs.

In certain regions, a few specific verbs are used in the preterite, for instance the modal verbs and the verbs haben (have) and sein (be).

• Es gab einmal ein kleines Mädchen, das Rotkäppchen hieß. (There was once a small girl who was called Little Red Riding Hood.)

In speech and informal writing, the Perfekt is used (e.g., Ich habe dies und das gesagt. (I said this and that)).

However, in the oral mode of North Germany, there is still a very important difference between the preterite and the perfect, and both tenses are consequently very common. The preterite is used for past actions when the focus is on the action, whilst the present perfect is used for past actions when the focus is on the present state of the subject as a result of a previous action. This is somewhat similar to the English usage of the preterite and the present perfect.

• Preterite: "Heute früh kam mein Freund." (my friend came early in the morning, and he is being talked about strictly in the past)
• Perfect: "Heute früh ist mein Freund gekommen." (my friend came early in the morning, but he is being talked about in the present)

The past perfect is used in every German speaking country and it is used to place an action in the past before another action in the past. It is formed with an auxiliary (haben/sein) and a past participle that is placed at the end of the clause.

Dutch mainly uses these two past tenses:

• onvoltooid verleden tijd, which matches the English simple past and the German preterite, for example: Gisteren was ik daar ("I was there yesterday").
• voltooid tegenwoordige tijd, a present tense with the meaning of perfect. This form is made by combining a form of zijn ("to be") or hebben ("to have") with the notional verb, for example: Gisteren ben ik daar geweest. This also means "I was there yesterday", but just as it is the case for English constructions with the present perfect simple, this kind of formulation puts more emphasis on the "being finished"-aspect.

Less common is the voltooid verleden tijd, which corresponds to the English past perfect. It is formed by combining an onvoltooid verleden form of zijn ("to be") or hebben ("to have") with the notional verb, for example: Ik was daar voor gisteren al geweest. This means "I had been there before yesterday." This tense is used to indicate that one action in the past occurred before another past action, and that the action was fully finished before the second action took place.

In non-Germanic Indo-European languages, past marking is typically combined with a distinction between perfective and imperfective aspect, with the former reserved for single completed actions in the past. French for instance, has an imperfect tense form similar to that of German but used only for past habitual or past progressive contexts like "I used to..." or "I was doing...". Similar patterns extend across most languages of the Indo-European family right through to the Indic languages.

Unlike other Indo-European languages, in Slavic languages tense is independent of aspect, with imperfective and perfective aspects being indicated instead by means of prefixes, stem changes, or suppletion. In many West Slavic and East Slavic languages, the early Slavic past tenses have largely merged into a single past tense. In both West and East Slavic, verbs in the past tense are conjugated for gender (masculine, feminine, neuter) and number (singular, plural).

French has numerous forms of the past tense including but not limited to:

• Past perfective (passé composé) e.g. J'ai mangé (I ate or I have eaten, using the form but usually not the meaning of I have eaten)
• Past imperfective (imparfait) e.g. Je mangeais (I was eating)
• Past historic or Simple past (passé simple) e.g. Je mangeai (I ate) (literary only)
• Pluperfect (Plus que parfait) e.g. J'avais mangé (I had eaten [before another event in the past])
• Recent past (passé recent) e.g. Je viens de manger (I just ate or I have just eaten)

Spanish and Portuguese have several forms of the past tense, which include but are not limited to:

• Preterite tense (préterito, pretérito) e.g. Yo comí and Eu comi (I ate or I have eaten)
• Past imperfective (imperfecto, imperfeito) e.g. Yo comía and Eu comia (I was eating)
• Pluperfect (pluperfecto, mais-que-perfeito) e.g. Yo había comido or Yo hube comido and Eu comera or Eu tinha comido (I had eaten [before another event in the past])

A difference in the pluperfect occurs between Spanish and Portuguese; in the latter, a synthetic pluperfect exists which follows the imperfect conjugations, but -ra replaces the -va seen in the verb endings.

In Belizean Creole, past tense marking is optional and is rarely used if a semantic temporal marker such as yestudeh "yesterday" is present.

Singaporean English Creole (Singlish) optionally marks the past tense, most often in irregular verbs (e.g., go → went) and regular verbs like accept which require an extra syllable for the past tense suffix -ed.

Hawaiian Creole English[6] optionally marks the past tense with the invariant pre-verbal marker wen or bin (especially older speakers) or haed (especially on the island Kauai). (Ai wen si om "I saw him"; Ai bin klin ap mai ples for da halade "I cleaned up my place for the holiday"; De haed plei BYU laes wik "They played BYU last week"). The past habitual marker is yustu (Yo mada yustu tink so "Your mother used to think so").

Haitian Creole[7] can indicate past tense with the pre-verbal marker te (Li te vini "He (past) come", "He came").
