The Transgender Style Guide
The Radical Copyeditors produced an excellent "Transgender Style Guide" for writers. It truly does an outstanding job of illustrating appropriate use of terminology as well as excellent recommendations around the use of names and pronouns.
The Style Guide answers questions such as:
How do I describe someone who is transgender?
What does gender nonconforming mean?
What pronoun should I use when describing someone who is transgender?
and also digs into explanations of relationships to body, anatomy, birth sex and more.
This is an outstanding resource for all of us, writers or not, to better understand how to communicate the diversity of our team members and guests.
