What is behind the qualification "remain" as a linking verb in the definition above?

-----------------

I'm a bit confused with that dictionary qualification. If you take that definition as it stands and substitute "need to be done/answered/collected" for "remain" accordingly, then, in my opinion, "need" isn't a linking verb.

I see "remain" as a non-copular verb, a verb with its own complements, "to be done/answered/collected", rather than a linking verb followed by subjects complements.

"Remain" can function as a linking verb, for example:


He is/remains satisfied.

He is/remains head of the company.

He is/remains qualified to lead the group.

He is/remains committed to the project.

Yes, I agree that in your examples subject complements follow the linking verb "remain". But in my post, there are clauses (non-finite ones) which I see as complements of the verb "remain" rather than subject complements.
