What is the plural possessive form of they?

Answer 1

The word 'they' is the plural personal pronoun, a word that takes the place of a plural noun as the subject of a sentence or a clause.

Example: The Walkers are my neighbors. They often stop by to visit.

There are two possessive forms of the pronoun 'they':

The possessive pronoun, a word that takes the place of a noun that belongs to a plural noun or two or more nouns, is theirs.

Example: The Walkers are my neighbors. The house on the corner is theirs.

The possessive adjective, a word that is placed before a noun to describe that noun as belonging to a plural noun or two or more noun, is their.

Example: The Walkers are my neighbors. Their houseis on the corner.
