The BBC introduced a Glossary for transgender terms as follows:
LGBT+: stands for lesbian, gay, bisexual and transgender. The plus sign represents other sexual and gender groups
Transgender: Applies to a person whose gender is different from their “assigned” sex at birth
Cisgender: Applies to someone whose gender matches their “assigned” sex at birth (ie someone who is not transgender)
Non-binary: Applies to a person who does not identify as “male” or “female”
Genderqueer: Similar to “non-binary” – some people regard “queer” as offensive, others embrace it
Genderfluid: Applies to a person whose gender identity changes over time.
“It’s fair to say many people don’t know how to speak to or about transgender people. So what do the terms involved mean and what’s considered polite”? The BBC also put together a Transgender guide defining the following terms.
Transgender man/transgender woman
