they

We don’t traditionally think of they as having synonyms, but there are several situations in which it can replace—or be replaced with—another word, phrase, or series of words.

Plural people and things

They is perhaps most commonly used as a plural pronoun referring to multiple people, as in Seven people made reservations, and they all showed up at the same time. It can also refer to multiple things, as in I moved the packages so they wouldn’t fall off the table. 

A singular person

They also has a long history of being used to refer to an unspecified individual or to a person whose gender and other personal details are unknown or irrelevant, as in If a student is absent, they must bring in a note when they return to school. Sentences like this sometimes use constructions like he or she, but the use of they has become very common in such instances, with many people preferring they as less awkward and more inclusive.

Nonbinary gender expression

A use of they that has become more widespread is as a personal pronoun for those who identify as nonbinary or whose gender identity exists between or beyond the spectrum of strictly male or female. Grammatically, it’s used in the same way as the gender-specific terms like he and she, but it’s gender-neutral. You can learn more about this below.

themselves

In some cases, the word themselves is used as another way of saying they or another form of it. It’s sometimes used in place of they or them after the words as, than, and but, as in They saw girls no older than themselves. It can also be used as an emphatic form of they or them, as in They—the students themselves—wrote the lesson. Singular forms include themself or theirself.
