What are cis and trans alternate types of? I don’t think it’s “gender identity” because wouldn’t that just be man, woman or nonbinary regardless of whether they’re cis or trans? Cis/trans just being a qualifier?
If the answer is “I am cis” or “I am trans”, what is the question?
Edit: Someone came up with the term “gender congruity” and (after looking up the definition of “congruity”) I think this describes what I’m talking about perfectly.
You’re not getting an answer to your question because the question, as stated, is incomprehensible. You’re asking for a “category of characteristic” that a pair of antonym adjectives “belong to”? That doesn’t make sense. They apply to a whole host of characteristics, because they’re not describing a specific characteristic, but how a characteristic relates to the whole. Just like “homo” and “hetero”; homozygous, heterogenous, homocystine, and heterophony are all words that use the “homo” or “hetero” prefix to describe how those words relate to other concepts in their category. It’s the same with “cis” and “trans”. The prefixes don’t “belong” to a category of characteristics, they explicitly exist outside of the characteristics of the words their modifying.
That’s the best I can do with the way you’ve chosen to phrase your question, and I admit it’s a reach, but your question is gibberish.
Male, female or nonbinary are a person’s gender.
White, black, asian (nonexclusively) are a person’s race.
Right, left are a person’s handedness.
Gay, straight, bi are a person’s sexual orientation.
Cis, trans are a person’s ________.
We could call it “gender metadata” ;p
I’m not actually sure if there’s a real term for this. If nothing else, “trans status” works but there should be a better term I think ^.^
Maybe “genderdivergence”?
I think it would have to be “Gender <something>” rather than a single word.
Gender modality
Cis and trans don’t really describe a person in the same way as the others. They describe a relationship between characteristics, which none of the other descriptors you list do. You could argue, almost correctly, that cis and trans are part of a person’s gender, but neither one of them is a person’s anything.
Hetero and homo describe a relationship between characteristics. Sexual preference and gender are both characteristics.
Gender prefixes?
Cis and trans are like homo and hetero - they are a part of the English language.
You can have homogenized milk; you can have trans fats.
You can also have homosexual, transgender, cisgender and heterosexual animals.
Gender identity.
I talked about that in the original post.
“gender identity” might fit. “Identity” taken literally, to mean if the birth sex/gender and the actual expressed gender are identical.
Edit: or “gender divergence” if you want to focus on the difference instead of the sameness.
