Identifying the Grammatical Class of 'school'

The question asks us to determine the grammatical class of the underlined word "school" in the sentence: "They are school children."

To identify the grammatical class of a word, we need to understand how it functions within the sentence. Let's look at the common grammatical classes:

• Noun: A word that represents a person, place, thing, or idea.
• Adjective: A word that describes or modifies a noun or pronoun.
• Verb: A word that represents an action, state, or occurrence.
• Adverb: A word that modifies a verb, adjective, or another adverb, often indicating manner, place, time, or degree.

In the sentence "They are school children," the word "children" is a noun. The word "school" comes before "children" and tells us what kind of children they are. It describes or modifies the noun "children". Words that describe or modify nouns are called adjectives.

Even though "school" can function as a noun (e.g., "I went to school"), in this specific sentence, it is acting like an adjective. This is a common grammatical feature where a noun is used before another noun to modify it, often called an attributive noun or noun adjunct. When used in this way, the noun functions grammatically as an adjective.

Let's consider the options provided:

• (a) Noun: While "school" can be a noun, in this sentence, it modifies "children", which is characteristic of an adjective.
• (b) Adjective: The word "school" is modifying the noun "children", describing the type of children. This is the function of an adjective.
• (c) Verb: "School" is not performing an action or indicating a state in this sentence.
• (d) Adverb: "School" is modifying the noun "children", not a verb, adjective, or adverb.

Therefore, based on its function in the sentence "They are school children," the word "school" belongs to the grammatical class of an adjective.

The correct grammatical class of the underlined word "school" is Adjective.
