Adjectives typically do not have participles.
That's true, but since a participle is an adjective formed from a verb, we are looking for a verb that means 'to get big.' 'Grown' and 'enlarged' come to mind. Or the one made famous by a fast food chain: 'SUPER-SIZED'.
Big is not a verb and does not have participle forms.
The past participle is had.
Done is the past participle.
No, the word old is an adjective, not a participle.
The past participle of the word "Find" is the word "Found."
The present participle of the word "go" is "going."
The past participle of the word "pick" is "picked".
The past participle of the word "finish" is "finished."
The present participle for the word 'hit' is 'hitting'.
No. The word "vast" is a straightforward adjective, not a participle.
The past participle of the word "touch" is "touched". It is a regular formation.
The past participle of the word 'be' is 'been'. 'They had been running fast for several minutes.'
