What is the participial phrase in this sentence "The boy sleeping in the corner is snoring loudly"?

1 Answer

"sleeping in the corner"

Explanation:

A participle phrase is a phrase that starts with a participle (if we're dealing with the present, then it'll be a word normally thought of as a verb and ends with -ing and if we're dealing with the past, then that verb-looking word will generally end01 in -ed) and goes on to describe a noun. It may look like a verb but the whole thing operates as an adjective - it modifies a noun.

In our question, we can rewrite it and eliminate the participle phrase:

The boy is snoring loudly.

Which is fine. But we want to say a little bit more about the boy. Where is he? And what else is he doing, aside from snoring loudly?

The boy sleeping in the corner is snoring loudly.

01 Irregular verbs, as pointed out by @Danial L., will not necessarily end in "-ed". The verb "sleep" for instance has as its past participle "slept" and not "sleeped".
