Theory:

phrase is a group of words that are together as a single unit, as part of a clause or a sentence.
A phrase does not contain a subject and verb and, so it cannot make a complete sentence. A phrase is not like a clause. A clause does contain a subject and a verb, and it can make a complete sentence.
Example:
1. As soon as you got in, he went out.
(As soon as is a conjunctional phrase.)

2. Popcorn popping, the dog was ready for the film.
Popcorn popping” modifies the clause “the dog was ready for the film.”

3. The entire rugby team, their uniforms muddy and stained, shouted in joy.
