If someone had an ecter instead of a gender, would they be considered agender?

yes, cuz they have no Gender and that’s what agender is referring to. if you had no ecter, the best and most simple word for it would prolly be “anecter.” you could also spell it as aecter, but i feel like anecter is way easier to say and read (a- / an- as a prefix have the same meaning, anyways)
