I wasn’t sure of the answer to this, so I reached out to Micah, at neutrois.me.
What’s the difference between agender and neutrois?
The definitions i’ve found don’t really make a clear distinction.
with Neutrois being “a neutral third gender; genderless, no gender identity, similar to agender; sometimes defined as a specific kind of genderless identity, including the experience of physical dysphoria.”
and agender being “a gender identity (or lack of a gender identity) meaning genderless, non-gendered”
The difference can’t be presence of dysphoria, can it?
There are many opinions on this matter. Some agender people feel neutrois describes them as well, some do not. Some agender people feel genderless or that they do not have a gender, others feel more gender-neutral or a third gender all together. Either can be accompanied by dysphoria - physical, social, otherwise - or not.
It really comes down to personal preference and personal application of the terms. So the best you can do is ask the person how they identify and what that means to them. If this is a question you are asking for yourself, I’d say choose the word that best resonates with you.
