Short for elizabeth
In French, the name "Betty" remains the same; it is typically used as a proper name without translation. However, if you are referring to the term "betty" as a slang for a good-looking woman, it doesn't have a direct equivalent in French. Instead, you might use "belle" (meaning beautiful) or "jolie" (meaning pretty).
