Is themselves a possessive plural pronoun?

Answer 1

No, the pronoun 'themselves' is a plural reflexive pronoun; a word that 'reflects' the noun antecedent. The reflexive pronouns are myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.

Example: The Lincolns painted the house themselves.

The reflexive pronouns also function as intensive pronouns, used to emphasize the noun antecedent.

Example: The Lincolns themselves painted the house.

A possessive pronoun takes the place of a noun that belongs to someone or something. The possessive pronouns are mine, yours, his, hers, its, ours, theirs.

Example: The Lincolns live on this street. The houseon the corner is theirs.

Another type of possessive pronoun is a possessive adjective, a word placed before a noun that shows something belongs to the antecedent. The possessive adjectives are: my, your, his, her, their, its.

Example: The Lincolns live on this street. Their house is on the corner.

Answer 2

No, "themselves" is a reflexive pronoun, not a possessive pronoun. It is used to refer back to the subject of a sentence and indicates that the subject is performing an action on themselves.
