Past tense

The past tense is a grammatical tense whose function is to place an action or situation in the past. Examples of verbs in the past tense include the English verbs sang, went and washed. Most languages have a past tense, with some having several types in order to indicate how far back the action took place. Some languages have a compound past tense which uses auxiliary verbs as well as an imperfect tense which expresses continuous or repetitive events or actions. Some languages inflect the verb, which changes the ending to indicate the past tense, while non-inflected languages may use other words meaning, for example, "yesterday" or "last week" to indicate that something took place in the past.

Introduction[edit]

In some languages, the grammatical expression of past tense is combined with the expression of other categories such as grammatical aspect (see tense–aspect). Thus a language may have several types of past tense form, their use depending on what aspectual or other additional information is to be encoded. French, for example, has a compound past (passé composé) for expressing completed events, and imperfect for continuous or repetitive events.

Some languages that grammaticalise for past tense do so by inflecting the verb, while others do so periphrastically using auxiliary verbs, also known as "verbal operators" (and some do both, as in the example of French given above). Not all languages grammaticalise verbs for past tense – Mandarin Chinese, for example, mainly uses lexical means (words like "yesterday" or "last week") to indicate that something took place in the past, although use can also be made of the tense/aspect markers le and guo.

The "past time" to which the past tense refers generally means the past relative to the moment of speaking, although in contexts where relative tense is employed (as in some instances of indirect speech) it may mean the past relative to some other time being under discussion.^[1] A language's past tense may also have other uses besides referring to past time; for example, in English and certain other languages, the past tense is sometimes used in referring to hypothetical situations, such as in condition clauses like If you loved me ..., where the past tense loved is used even though there may be no connection with past time.

Some languages grammatically distinguish the recent past from remote past with separate tenses. There may be more than two distinctions.

In some languages, certain past tenses can carry an implication that the result of the action in question no longer holds. For example, in the Bantu language Chichewa, use of the remote past tense ánáamwalíra "he died" would be surprising since it would imply that the person was no longer dead.^[2] This kind of past tense is known as discontinuous past. Similarly certain imperfective past tenses (such as the English "used to") can carry an implication that the action referred to no longer takes place.^[3]

A general past tense can be indicated with the glossing abbreviation PST.

The 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.

simple past

The (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).

past progressive

The 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.

past perfect

The (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.

past perfect progressive

The expression (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.

African languages[edit]

While in Semitic languages tripartite non-past/past imperfective/past perfective systems similar to those of most Indo-European languages are found, in the rest of Africa past tenses have very different forms from those found in European languages. Berber languages have only the perfective/imperfective distinction and lack a past imperfect.

Many non-Bantu Niger–Congo languages of West Africa do not mark past tense at all but instead have a form of perfect derived from a word meaning "to finish". Others, such as Ewe, distinguish only between future and non-future.

In complete contrast, Bantu languages such as Zulu have not only a past tense, but also a less remote proximal tense which is used for very recent past events and is never interchangeable with the ordinary past form. These languages also differ substantially from European languages in coding tense with prefixes instead of such suffixes as English -ed.

Other, smaller language families of Africa follow quite regional patterns. Thus the Sudanic languages of East Africa and adjacent Afro-Asiatic families are part of the same area with inflectional past-marking that extends into Europe, whereas more westerly Nilo-Saharan languages often do not have past tense.

Asian languages[edit]

Past tenses are found in a variety of Asian languages. These include the Indo-European languages Russian in North Asia and Persian, Urdu, Nepali and Hindi in Southwest and South Asia; the Turkic languages Turkish, Turkmen, Kazakh, and Uyghur of Southwest and Central Asia; Arabic and Hebrew in Southwest Asia; Japanese; the Dravidian languages of India; the Uralic languages of Russia; Mongolic; and Korean. Languages in East Asia and Southeast Asia typically do not distinguish tense; in Mandarin Chinese, for example, the particle 了le when used immediately after a verb instead indicates perfective aspect.

In parts of islands in Southeast Asia, even less distinction is made, for instance in Indonesian and some other Austronesian languages. Past tenses, do, however, exist in most Oceanic languages.

The Americas[edit]

Among Native American languages there is a split between complete absence of past marking (especially common in Mesoamerica and the Pacific Northwest) and very complex tense marking with numerous specialised remoteness distinctions, as found for instance in Athabaskan languages and a few languages of the Amazon Basin. Some of these tenses can have specialised mythological significance and uses.

A number of Native American languages like Northern Paiute stand in contrast to European notions of tense because they always use relative tense, which means time relative to a reference point that may not coincide with the time an utterance is made.

New Guinea[edit]

Papuan languages of New Guinea almost always have remoteness distinctions in the past tense (though none are as elaborate as some Native American languages), whilst indigenous Australian languages usually have a single past tense without remoteness distinctions.
