Can You give me an example of particial phrase?

You're asking about a "particial phrase," but that's not a standard grammatical term. It seems like you might be thinking of a participial phrase, which is a group of words containing a participle (a verb ending in "-ing" or "-ed") and its modifiers.

Here's an example:

"Walking down the street, I saw a beautiful flower blooming."

* Walking down the street is the participial phrase.

* Walking is the participle, acting as an adjective modifying "I."

* down the street is the modifier of the participle.

Participial phrases can add detail and description to a sentence, and they can be placed at the beginning, middle, or end of a sentence.
