A few more #gender words as #Gaeilge:
Gender itself is 'inscne.'
Transgender is 'trasinscneach.'
Cis is... just cis, afaik. Latin gonna Latin.
Agender is 'gan inscne.'
Queer is 'aiteach.'
If you want to say 'I am a trans man/woman/person,' you would say 'is fear/bean/duine tras mé.'
If you want to say 'I am nonbinary,' you would say 'tá mé neamh-dhénártha.'
