Question

Which words in the sentence form the participial phrase?

Sitting patiently, my mother read a magazine in the waiting room

Answer 1

A participle is a verbal ending in -ing (present) or -ed, -en, -d, -t, -n, or -ne (past) that functions as an adjective, modifying a noun or pronoun. I think Sitting patiently is the answer.
