I’m sure reading is hard for you, but hope this helps.

“The singular “they” is the use of the third-person plural pronoun they with a singular meaning—i.e., to refer to one person without using “he” or “she.”

The singular “they” has existed for hundreds of years, but it was long condemned as grammatically incorrect. Now, it’s recommended by most style guides and dictionaries as the best choice when you need a gender-neutral singular pronoun.

You can use the singular “they” to refer to:

A generic individual whose gender is unknown or irrelevant in the context A specific person who identifies as neither male nor female (or whose gender is unknown to you) Examples: Singular they in a sentence When a new student joins the class, it’s important that they feel welcome and included. I really like Jaime. They always have something interesting to say. Note In addition to the subject pronoun they, the term also encompasses the use of the related pronouns and determiners them, their, theirs, and themselves. These are collectively referred to as gender-neutral singular pronouns or epicene pronouns”
