‘Them’ is a pronoun. More specifically, it is a personal pronoun that is used to refer to a group of people or things that have already been mentioned or are easily identified in context.
In English, pronouns are words that substitute for nouns. They can represent subjects, objects, or possessives of a sentence. ‘Them’ is used as an object pronoun, meaning it typically serves as the object of a verb or a preposition. For example, in the sentence ‘I saw them at the park,’ ‘them’ is the object of the verb ‘saw.’
This pronoun is also the plural form of ‘him’ and ‘her,’ and it does not change based on the grammatical case; it remains ‘them’ regardless of its role in the sentence. This makes ‘them’ an essential part of the English language for effective communication.
