Transgender
(adj)
Transgender (or 'trans' for short) is an adjective that refers to individuals whose gender identity differs from that associated with their sex assigned at birth (Source).
It is important to use the term 'transgender' as an adjective rather than a noun (such as 'a transgender') or a verb (such as 'transgendered') which is outdated and considered offensive. Other words to avoid include: 'biologically male/female,' 'born a woman/man,' 'real woman/man,' 'genetically male/female,' etc.
Example: An individual who was assigned male at birth (AMAB), and whose gender identity is woman, might introduce themselves as a trans woman, transgender woman, or simply a woman.
Why it’s important to know this: By having the language to describe transgender identities, we avoid simply categorizing them as ‘other’ or ‘weird,’ and acknowledge these gender identities as a part of the range of human experiences. Additionally, the United States Department of Education, the National Education Association, and the American Federation of Teachers, have all expressed a commitment to safe, supportive, and affirming schools for transgender and nonbinary students and provide guidance to school staff (Source, source, source).
