Aliagender

Aliagender (from Latin alius, "other" ) is “A gender experience which is 'other', or stands apart from existing gender constructs.” It is a specific nonbinary identity which is not a mixture of male and female, nor an absence of gender, but instead a strong, specific gender identity other than man or woman. This term is used by people who would identify as "third gender," but who don't want to appropriate any culture-specific gender identity implied by the term "third gender."

History
A moderator on the askanonbinary Tumblr blog created the word "aliagender" in response to Tumblr user Zobothehobo. Zobothehobo later described this event: "i was there when aliagender was coined. actually, i was the reason it was coined. I sent messages to askanonbinary and beck came up with the word. we defined it then as a gender experience other from the traditional spectrum. I always meant for this to be a term for a specific positive gender that was not associated with the man/woman spectrum, but was a gender that existed and NOT genderless."

Soon after, there was a conflict about whether the word was politically problematic. Some people of color reportedly said "that aliagender is racist in that it is basically just a whitewashed version of third gender." In response, another person coined "aporagender" as an alternative to aliagender, due to concerns that aliagender might be "racist or appropriative." Zobothehobo said "they did not intend for aliagender to be harmful in anyway, and was created to describe an 'othering' concept of gender."
