For singular, non-binary individuals:
* They: This is the most common and widely accepted option.
* Themselves: While this technically refers to multiple people, it can be used as a singular pronoun in informal contexts.
* Theirself: This is a less common but increasingly accepted alternative to "themself" that emphasizes singularity.
For groups:
* Themselves: This is the most common and correct option when referring to a group of people.
Other options:
* The person: This emphasizes the individual.
* The individual: This is more formal.
* The person in question: This is more specific.
* The one: This is more poetic.
Example:
* "They went to the store by themself." (singular, non-binary individual)
* "The children played by themselves." (group)
It's always best to be mindful of the person you are referring to and use the pronoun they feel most comfortable with.
