Gender-neutral language
Gender-neutral language is language that does not show bias towards any gender, like saying "he" or "she" when talking about someone who you don't know is male or female. Instead of those words, people use terms like "they" and "them" when talking about someone whose gender they don't know. This shows respect to people of all genders and lets everyone feel included.
