using the adjective trans in the context trans woman is equally ridiculous
Using "trans" as an adjective is ridiculous in itself, and evidence of another subtle but dangerous shift in the use of language hat we are being lured into.
"Trans" is NOT an adjective - it is a prefix.
The trans community itself used it as a prefix initially. Any comments that "trans-women/transwomen (prefixes JOIN the word) are men" and that "trans" was meaningless, were met with "IT'S A LATIN PREFIX, YOU BIGOTS! LOOK IT UP! EDUCATE YOURSELVES!" And indeed it IS a Latin prefix - used in chemistry - it literally means "on the other side of", so transalpine Gaul, was the area of Gaul on the other side of the Alps. Trans-women are therefore "women" on the other side of . . . I don't know . . . sanity?
A prefix generally very often changes the meaning of a word to its opposite (eg noble/ignoble; moral/amoral, boss/ ex-boss). This could be argued to apply here, where TW are the opposite of women.
Then, possibly realising this, the "trans" became separated from the second part of the word "woman"/ "man" and SUDDENLY WAS BEING USED AS AN ADJECTIVE. The implication then was that a "trans" woman was just another kind of woman - a simple description - in the same way that a black woman, or a tall woman, or a blonde woman were just different descriptions of different women. And they gave this more power with the forced coupling with "cis". (If you aren't "trans", you're "cis" - whether you want to be or not, because it validates "trans")
The truth is that there are only women and men. Men in frocks aren't women. Women in trousers aren't men. NOBODY changes SEX.
"Trans" is a prefix. It is one being used out of context, but it remains a prefix, not an adjective.
Attached to the word "women" it emphasises that these are men.
