is there gender sfor clouds and waves? I'd suggest nuagender (nuage is cloud in french) or pilvigender (in finnish) and ondagender (wave in portuguese)
i haven’t heard of any for waves specifically (there’s a few for the ocean in general and one for tides), so feel free to coin ondagender, but for clouds theres nubegender: a gender that is very similar to the movement of clouds. Some days, one's gender is completely clear, similar to being genderless. However, formations of different attributes will float into one's gender, moving across until out of sight, like clouds in the sky. Sometimes, these formations look like certain genders, and sometimes they are fuzzy and abstract. Sometimes they cover your whole gender experience and overwhelm it.
