Themselves or Theirselves – Which is Correct?

Pronouns are a useful tool that writers use to make sentences more fluid by avoiding redundancy. Instead of writing, for instance, “Gregory left Gregory’s house and got into Gregory’s car to go to Gregory’s job,” we can simply write, “Gregory left the house and got into his car to go to work.”

Reflexive pronouns are a specific type of pronoun that are useful under certain conditions, but they can be confusing, too. Many people aren’t sure whether to use themselves or theirselves as a plural reflexive pronoun.

When to Use Themselves

Definition of theirselves definition of themselves definitionWhat does themselves mean? Themselves is a plural pronoun. Since it is used reflexively, it is used in contexts where the subject of a sentence is also its object. And since it is plural, it refers to more than one person.

For example,

  • They fooled themselves into thinking they could win, but they never had a chance.
  • “Who will guard the guards themselves?” goes the old Latin proverb.

Other reflexive pronouns include himself, herself, and myself. Reflexive pronouns can be used as intensive pronouns, where they add emphasis or specify who will do something.

For example,

  • The Republicans themselves did not expect to win the 2016 presidential election.

Many languages have reflexive pronouns, including Chinese, Spanish, French, Hungarian, and Slovene.

In English, reflexive pronouns are sometimes used non-reflexively, especially in professional writing.

A more graceful phrasing would be,

  • Please CC Donna and me on the email.
