Final answer:
In the sentence provided, the pronoun 'them' is plural, referring to more than one person. Pronouns such as 'they,' 'their,' and 'them' are also being increasingly used in a singular gender-neutral context, but 'them' in this scenario is plural.
Step-by-step explanation:
In the sentence 'Go to work with them,' the highlighted pronoun 'them' is a plural pronoun. This pronoun is used to refer to more than one person or thing. It is important to use plural pronouns correctly to maintain clarity in communication. While pronouns like 'they,' 'their,' and 'them' can also be used as singular gender-neutral pronouns, in this context, 'them' is used as a plural pronoun.
In contemporary usage, pronouns are evolving, and the use of 'they/them/theirs' as singular pronouns is becoming more accepted to refer to nonbinary or transgender people, or when the gender of the person is unknown. However, with collective nouns such as 'team' or 'group,' the pronoun can be singular or plural depending on whether the group acts as a single unit or its members act individually.
