Past tense

The past tense is a grammatical tense whose principal function is to place an action or situation in past time. In languages which have a past tense, it thus provides a grammatical means of indicating that the event being referred to took place in the past. Examples of verbs in the past tense include the English verbs sang, went and was.

In some languages, the grammatical expression of past tense is combined with the expression of other categories such as mood and aspect (see tense–aspect–mood). 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, an imperfect for expressing events which were ongoing or repeated in the past, as well as several other past forms.

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.

English grammar

English grammar is the structure of expressions in the English language. This includes the structure of words, phrases, clauses and sentences.

There are historical, social, cultural and regional variations of English. Divergences from the grammar described here occur in some dialects of English. This article describes a generalized present-day Standard English, the form of speech found in types of public discourse including broadcasting, education, entertainment, government, and news reporting, including both formal and informal speech. There are certain differences in grammar between the standard forms of British English, American English and Australian English, although these are inconspicuous compared with the lexical and pronunciation differences.

Word classes and phrases

Eight types of word ("word classes" or "parts of speech") are distinguished in English: nouns, determiners, pronouns, verbs, adjectives, adverbs, prepositions, and conjunctions. (Determiners, traditionally classified along with adjectives, have not always been regarded as a separate part of speech.) Interjections are another word class, but these are not described here as they do not form part of the clause and sentence structure of the language.

Simple past

The simple past or past simple, sometimes called the preterite, is the basic form of the past tense in Modern English. It is used principally to describe events in the past, although it also has some other uses. Regular English verbs form the simple past in -ed; however there are a few hundred irregular verbs with different forms.

The term "simple" is used to distinguish the syntactical construction whose basic form uses the plain past tense alone, from other past tense constructions which use auxiliaries in combination with participles, such as the past perfect and past progressive.

Formation

Regular verbs form the simple past in -ed; however there are a few hundred irregular verbs with different forms. For details see English verbs: Past tense.

Most verbs have a single form of the simple past, independent of the person or number of the subject (there is no addition of -s for the third person singular as in the simple present). However, the copula verb be has two past tense forms: was for the first and third persons singular, and were in other instances. The form were can also be used in place of was in conditional clauses and the like; for information on this, see English subjunctive. This is the only case in modern English where a distinction in form is made between the indicative and subjunctive moods in the past tense.

Past

The past is a term used to indicate the totality of events which occurred before a given point in time. The past is contrasted with and defined by the present and the future. The concept of the past is derived from the linear fashion in which human observers experience time, and is accessed through memory and recollection. In addition, human beings have recorded the past since the advent of written language.

The past is the object of such fields as history, memory, flashback, archaeology, archaeoastronomy, chronology, geology, historical geology, historical linguistics, law, ontology, paleontology, paleobotany, paleoethnobotany, palaeogeography, paleoclimatology, and cosmology.
