Q: Do trans [people] know I reject your trans non-word cisgender?

Note: Quora moderation removed this question for inappropriateness as I was writing my answer.

Do trans know I reject your trans non-word cisgender? It’s a lie, it’s an offensive term and put down.

Ok quick lesson: “Trans-“ is a Latin prefix meaning “on the other side”. “Cis-“ is a Latin prefix meaning “on the same side”. They are perfect antonyms.

In the context of your question, “trans” is short for “transgender”, which is an adjective. Adjectives are used to provide more information about a noun, which you failed to provide, making your sentence ungrammatical. You wouldn’t ask a question like “Do tall know I reject your tall non-word short?”, would you?

Let’s fix your question: “Do transgender people know I reject your transgender non-word ‘cisgender’?” There, now it’s grammatical. Now I can answer your question.

As a trans person, I’ve read your question, so I can answer truthfully, “yes, at least one trans person knows you reject ‘cisgender’.” But that leads me to ask you “am I supposed to care?”

First, your premise that “cisgender” is a “non-word” is flawed. A “non-word” definitely wouldn’t appear in dictionaries, would it? Yet a quick search yields multiple dictionary entries, such as:

• Definition of CISGENDER (Merriam-Webster)
• Definition of cisgender | Dictionary.com (dictionary.com)
• cisgender adjective – Definition, pictures, pronunciation and usage notes (Oxford)

“Cisgender” is very obviously a not a “non-word”.

Next, as the appearance of the word “cisgender” in multiple mainstream dictionaries demonstrates, it is not a “trans” word – it is very much in the mainstream of the English language.

So your question becomes: “Do transgender people know I reject the very real, very mainstream actual-word ‘cisgender’?” This question is really quite silly, isn’t it?

Perhaps we can glean more context from your follow-on sentence: “It’s a lie, it’s an offensive term and put down.”

In your sentence, you make three claims:

1. “[’cisgender’ is] a lie”. In what way is “cisgender” a lie? It is a word. A word cannot be a lie unless the word itself is the word “lie”. “Cisgender” has a meaning, which either applies to the subject noun or it does not. Perhaps you’re meaning that the application of “cisgender” to a specific noun is incorrect, but if so, you’ve not provided any noun for us to evaluate the applicability of the adjective “cisgender”, so at best, your statement is incomplete.
2. “[‘Cisgender’ is] an offensive term”. How so? To whom is it offensive? In what way? “Cisgender” is a description of a potential attribute of a person, same as “tall”, “smart”, or “polite”. I’m over 6 feet in height, so while I could claim to reject the word “tall”, it would still be applicable to me. I could even claim to take offense to the word “tall” being applied to me, but that still wouldn’t make it an offensive word.
3. “…and [‘Cisgender’ is a] put down”. This is similar to #2 in that you’ve not explained how it is a put down. Further, if we were to accept your premise that it is offensive (which we do not), wouldn’t that mean that it’s also an insult — a.k.a. a “put down”? This just makes this point repetitive and unnecessary.

Since you haven’t offered any context for your follow-on statement, I’ll infer from both your question and the follow-on sentence that you feel some animosity towards transgender people. Perhaps you want to make it absolutely crystal clear that you want nothing to do with transgender people. Wouldn’t it be handy to have a word which could communicate the idea “definitely not transgender”?

Well, you’re in luck, because I happen to know that there is indeed, a word which means the exact opposite of “transgender”, which you can use to quickly and easily make clear that you are most definitely not transgender! Allow me to humbly present to you the perfect word for you to use for this purpose: “cisgender”.
