They/them/their
‘One of many sets of gender-neutral singular pronouns used as an alternative to she/her/hers or he/him/his.’
‘Queer There And Everywhere’ by Sarah Prager
Personal accounts
“It is important that people understand this is a usually third person pronoun that can be used to describe a singular person and it is not difficult to use it in this way.”
“Although I don’t use these pronouns myself, conversations I’ve had with friends that use these have shown me how difficult it is for people to respect them. People don’t tend to understand what being non-binary is and take this as a reason to not respect their pronouns ”
