Etymology
Currogender comes from the Latin word curre, meaning run.

Pronunciation

 * Currogender is a gender that feels like it runs away whenever you try to describe it, like a shy wild animal. It is a solid gender, but it just seems to disappear when you try to talk about it. It feels like it is always pulling away when you mention or think of it. It may approach again slowly after you stop thinking about it before becoming a part of your identity again. - blurgender, 2021
