Here's why:
* Gender-neutral language: In modern English, we strive for gender-neutral language. "Traitor" is already a gender-neutral term.
* Historically: While some languages may have had feminine forms for "traitor," English doesn't have a strong tradition of using gendered nouns for this type of word.
Instead of trying to find a feminine form, you can use:
* The word "traitor" itself: As mentioned, it's gender-neutral.
* Alternative phrases: You could use phrases like "someone who betrayed their trust," "a person who committed treason," or "a betrayer."
It's important to use language that is inclusive and avoids unnecessary gender distinctions.
