Is our a proper noun

Answer 1

No, the word 'our' is pronoun, a possessive adjective.

A noun is a word for a person, a place, or a thing,

A possessive adjective is a word that is placed before a noun to describe that noun.

The possessive adjectives are: my, your, his, her, its, our, their.

The possessive adjective 'our' is the first person, plural form.

Example: Jack and I are spending the weekend at our camp, (the pronoun 'our' describes the noun 'camp' as belonging to the speaker and Jack)
