Concept
Simple past
Summary
The simple past or past indefinite, 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.
Regular verbs form the simple past end-ed; however there are a few hundred irregular verbs with different forms. The spelling rules for forming the past simple of regular verbs are as follows: verbs ending in -e add only –d to the end (e.g. live – lived, not *liveed), verbs ending in -y change to -ied (e.g. study – studied) and verbs ending in a group of a consonant + a vowel + a consonant double the final consonant (e.g. stop – stopped). For details see .
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 inversion, negations with not, and emphatic forms of the simple past use the auxiliary did. For details of this mechanism, see do-support. A full list of forms is given below, using the (regular) verb help as an example:
Basic simple past:
I/you/he/she/it/we/they helped
Expanded (emphatic) simple past:
I/you/he/she/it/we/they did help
Question form:
Did I/you/he/she/it/we/they help?
Negative:
I/you/he/she/it/we/they did not (didn't) help
Negative question:
Did I/you/he/she/it/we/they not help? / Didn't I/you/he/she/it/we/they help?
Base form
Affirmative (+)
S + verb(ed) + c
Negative (-)
S + did not ( didn't) + verb + C
The simple past is used for a single event (or sequence of such events) in the past, and also for past habitual actions:
He took the money and ran.
