Question

Which of the following is an adjectival phrase in the sentence?

The overly excited children rushed into the front room with coloring books and new crayons.

Answer 1

An adjective is described by Oxford Languages as,
"a word or phrase naming an attribute, added to or grammatically related to a noun to modify or describe it."
A noun is as we all know, a person, place, or thing.
To find the adjective simply just find the noun in the sentence and look to see the word that's describing/modifying the sentence.
"children" would be the noun in the sentence. Behind that is "overly excited" which describes the children.

That step by step process leads us to our answer, "overly excited"
I hope this helped you understand the simple process.

Answer 2

The adjectival phrase in the sentence is "overly excited". It modifies the noun "children" by providing more information about the type of children who rushed into the front room.
