What are pronouns?
Pronouns - A word or phrase that may be substituted for a noun or noun phrase.
Example: ___ went to the store.
I, he, she, we, they, who, whoever, etc,. all qualify and are, therefore, subject pronouns.
EVERYONE has pronouns they would like to be used over others. Cisgender, transgender, gender non conforming, etc. It's all up to you to probe a bit and ask which they would like you to use. Do not assume someones gender or preferred pronouns. No matter how they look or express themselves. Not every girl is feminine, not every guy is masculine, and so on. If you want someone to use your correct pronouns, ask for theirs. It's okay to ask!
