Question

Identify the type of subordinate clause in the following sentence.

I guess what you did last night really wasn't that interesting.

Answer 1

I would say it's "what you did last night wasn't interesting.". Basically a subordinate clause is a sentence with a subject and a verb(action word) that can't be alone because it wouldn't be expressed well enough. more info--> http://www.grammar-monster.com/glossary/subordinate_clause.htm
