In the sentence....They have done nothing wrong. I know "have done" is part of the verb phrase but not sure if "wrong" is part of the verb phrase too. Would "wrong" be included in the verb phrase?

Answer 1

No.

The whole verb is "have done" while "wrong" is an adjective modifying the direct object, "nothing."

subject = They
verb = have done
direct object = nothing
adjective modifying DO = wrong
