The past tense is a grammatical form that expresses action or state that occurred in the past. In English, the past tense is usually marked by the addition of an "-ed" suffix to the verb, although there are some verbs that have irregular forms.Verbs that end in "-ed"Regular verbsRegular verbs follow a pattern where the past tense is formed by adding an "-ed" suffix to the present tense form. Here are some examples:talk (present tense) → talked (past tense)walk (present tense) → walked (past tense)write (present tense) → wrote (past tense)swim (present tense) → swam (past tense)###Exceptions to the "-ed" ruleThere are a few verbs that do not follow the "-ed" pattern. Instead, they maintain the same form in the past tense as they do in the present tense. Here are some examples:go (present tense) → went (past tense)do (present tense) → did (past tense)eat (present tense) → ate (past tense)take (present tense) → took (past tense)Verbs with irregular past tensesSome verbs have irregular past tense forms that do not follow the standard "-ed" pattern. Instead, their past tense forms maintain a different set of endings or bases. Here are some common irregular verbs and their past tense forms:bewas, were (present tense: am, are)bringbrought (present tense: bring)buybought (present tense: buy)catchcaught (present tense: catch)dodid (present tense: do)eatate (present tense: eat)findfound (present tense: find)gowent (present tense: go)havehad (present tense: have)knowknew (present tense: know)makemade (present tense: make)putput (present tense: put)runran (present tense: run)saysaid (present tense: say)seesaw (present tense: see)taketook (present tense: take)writewrote (present tense: write)Uses of the past tenseThe past tense is used to express an action or event that occurred in the past and is completed. It is often used in sentences with time markers such as yesterday, last night, in 2022, or during their vacation. Here are some examples:We talked on the phone last night. (indicating a conversation took place in the past)She swam across the pool in under a minute. (referring to an action that occurred in the past and is completed)They visited their grandparents last weekend. (action that occurred in the past during a specific timeframe)
