Question

"He hasn't shown up here because he called off the party". Put parentheses around the adverb clause!

Answer 1

adverb clause is a group of words that is used to change or qualify the meaning of an adjective, a verb

Answer 2

Yes. Adverb clauses are the parts of a sentence that add extra detail to what someone/thing is or doing. A good example of an adverb clause would be in "Doodle used to hide bodies until she got kind of tired of it and stopped because she was bored." The adverb clause would be "until she got kind of tired of it and stopped because she was bored."

Make sense?
