In the sentence the homework was easier for Tyrone after he received the chapter.

Is the dependent clause was easier for Tyrone?

Is that a noun since it is a predicate noun?

No. Please study the site I posted for you.

I promise I have! It is just not making any sense to me!

Remember that a clause must have a subject and verb.

Dependent clause after he reviewed the chapter

Adverb it modifies when it was easier?

Right.

Thanks.

The dependent clause in the sentence "the homework was easier for Tyrone after he received the chapter" is not "was easier for Tyrone." The dependent clause in this sentence is "after he received the chapter."

The phrase "was easier for Tyrone" is the predicate, specifically the predicate adjective phrase, describing the subject "the homework." It is not a noun, as it is describing the quality or state of the subject. In this case, it is describing the level of difficulty of the homework.
