what pronoun is we

Some nouns sound like they should be plural but are actually singular. If a noun needs a singular verb, then it should also get a singular pronoun.
The doctor treated his or her patients with dedication. (A doctor can be male or female, so you must use both gender singular pronouns)

There are some pronouns that are always subjective and others that are always objective.
Sometimes, determining which pronoun we should use in a sentence can be a little confusing, especially when it comes to I and me. You might want to write:

Yes, “we” is a personal pronoun, a word that takes the place of a noun (name) for specific people (the person speaking and one or more other people).
A personal pronoun is a pronoun that takes the place of a noun for a specific person or thing.
