What is the difference between they and them?

Answer 1

It's basically the same thing, it really depends on context in which you use the word "they" or "them". "They" is used when it is the subject (e.g. they are stupid) whereas "them" is used as a direct object (e.g. I hate them). But, remember English is a strange language and there is almost an exception to every rule, I guarantee it.

Answer 2

The personal pronoun 'they' is a subject pronoun, a word that functions as the subject of a sentence or a clause.

The personal pronoun 'them' is an object pronoun, a word that functions as the object of a verb or a preposition.

Examples:

They saw the boys. (subject of the sentence)

The boys that they saw were going to school. (subject of the relative clause)

A crossing guard helped them across the street. (direct object of the verb 'helped')

The boys had backpacks with them. (object of the preposition 'with')

Answer 3

"They" is a pronoun used to refer to a group of people or things. "Them" is the objective form of "they" and is used as the object of a verb or preposition in a sentence.
