complement clause

He is where he should be.

Adverb clause - yes.
complement of verb - yes.

vsureshHi Please tell me if this is a complement of be verb and also adverb clause.He is where he should (be).

It's not a complement. It's an adverbial. It doesn't complement the subject "He".

Thank you, Alphecca Stars.
Can we call it 'complement clause'?

vsureshPlease tell me if this is a complement of be verb and also adverb clause.

Where he should be is indeed a complement of the verb is, but it is not an adverbial clause because it is not a modifier.

Thank you, Aspara Gus
Then, what kind of clause is it?

In my opinion it is adverbial which doesn't have to be a modifier; an adverb has to be.
