I’m currently going over the copyedits of my next book, where the astute copyeditor tells me in her notes that “blonde” is only used for female people, but that the “regular” form is “blond.” Likewise with brunette/brunet.
I had no idea.
I asked Betty if she found the spelling blond and brunet odd, too, and she did as well, which leaves me with only one conclusion: we just don’t refer to men as their hair color. Double standard, anyone?
