Those that were in need of help were lucky to have Christian to assist them. I know the dependent clause is that were in need of help
I think the clause is a noun clause Is that correct?
Right. The clause is the subject of the verb, "were."
Thank you ! I was confused because the sentence started with those.
Oh darn! I got careless. Sorry!
The clause beginning "that" is an adjective clause modifying "those."
Actually, the clause "that were in need of help" in the sentence "Those that were in need of help were lucky to have Christian to assist them" is not a noun clause. It is an adjective clause (also known as a relative clause) because it starts with the relative pronoun "that" and functions to describe or modify the noun "Those."
To identify an adjective clause, you can ask yourself "What kind?" or "Which one?" about the noun it modifies. In this case, the clause describes or specifies which ones were lucky to have Christian's assistance: those who were in need of help.
