Misgendering
‘Misgendering’ means that a person is addressed in a way that does not correspond to their gender. This means, for example, that the wrong pronouns (he/she) or the wrong form of address (Mr/Mrs) are used. This usually happens because it is assumed that we can recognise each person's gender and that there are only two genders, namely female and male. Especially for people who use no or neutral pronouns and a neutral form of address, being misgendered is an everyday experience.
Respectful behaviour includes taking into account that another person's gender identity cannot be determined by their name or appearance. The preferred name as well as the gender identity and thus pronouns of a person should be found out and then used in verbal and written communication.
