. PAST PARTICIPLE
The past participle of a verb is the one we use with have / has and is / are.
It is usually the same as the regular past tense ending with 'ed', such as worked or started.
I have worked hard.
She has started work.
Sometimes irregular verbs have past participles that are different to the past tense.
For example, the past tense of see is saw, but the past participle is seen.
I see you. (present)
I saw you yesterday. (past)
I’ve seen you many times. (past participle making a present perfect tense)
ANNE
I haven’t seen him in two years.
