/məks/ /mɪks/noun
A title used before a person’s surname or full name by those who wish to avoid specifying their gender or by those who prefer not to identify themselves as male or female: the bank is planning to introduce the honorific ‘Mx’ as an alternative for anyone who feels that they don’t, for reasons of undetermined gender, fit into being either a Mr, Mrs, Miss or a Ms...
- A council is to include the title 'Mx' on its official forms to be more accommodating to the trans-community.
- To me, Mx Bond embodies the very best kind of girl a boy could ever grow up to become.
- Brighton & Hove council adopted the trans-friendly Mx title in 2013, after an inclusivity panel made the recommendation.
