Indefinite pronoun

Both worked hard.

Is "both" the indefinite pronoun?

Yes.

correct

Yes, the answer should be both! :)

No, "both" is not an indefinite pronoun. It is actually a pronoun used to refer to two people or things together.

An indefinite pronoun, on the other hand, refers to a nonspecific person or thing. Some common examples of indefinite pronouns include "someone," "anyone," "everyone," "everything," "nothing," "somebody," "nobody," and "anybody." These pronouns are used when the speaker does not want to specify or does not know the exact person or thing they are referring to.

To identify an indefinite pronoun, you can look for pronouns that do not specify a particular person or thing. In the given sentence, "both" is not unspecified or nonspecific, as it specifically refers to two people or things.
