Most past particples are the same as the simple past form, usually made by adding '-ed' to the end of the verb.
Verb | Simple Past | Past Participle | |
---|---|---|---|
Look | I looked | I have looked | |
Walk | I walk | I have walked | |
Read | I read | I have read | |
Cook | I cooked | I have cooked |
However, there are many verbs that don't follow this rule. These are called irregular past participles. Here are some examples of the most commonly used irregular verbs.
Verb | Simple Past | Past Participle | |
---|---|---|---|
eat | I ate | I have eaten | |
be | I was / were | I have been | |
take | I took | I have taken | |
see | I saw | I have seen | |
get | I got | I have gotten | |
buy | I bought | I have bought | |
begin | I began | I have begun | |
choose | I chose | I have chosen | |
ride | I rode | I have ridden | |
know | I knew | I have known | |
go | I went | I have gone |
Irregular past participles are used the exact same way as regular past participles are.
