25. Which word from the following sentence is a noun? The bird flew across the blue sky.
Answer: C
The word "bird" is a noun in the sentence.
In the sentence "The bird flew across the blue sky," the word "bird" functions as a noun, representing a living creature.
A) across
The word "across" is a preposition in this context, indicating the direction of the action. It does not denote a person, place, thing, or idea, which are the characteristics of a noun.
B) flew
"Flew" is the past tense of the verb "fly," describing the action performed by the subject. Verbs express actions or states of being, and therefore do not qualify as nouns.
C) bird
"Bird" is a noun as it names a specific type of animal. It serves as the subject of the sentence, making it the correct choice among the options provided.
D) blue
The word "blue" is an adjective that describes the color of the sky. Adjectives modify nouns and do not serve the function of a noun themselves.
Conclusion
The word "bird" is definitively the only noun in the sentence, as it identifies a specific entity. The other options do not fulfill the criteria of a noun, as they represent actions or descriptive qualities rather than naming a person, place, or thing.
