I learned a new French word today.
It can be either a masculine or feminine noun or an adjective, and it means “music-lover.” More accurately, it means “music mad,” in the same vein as pyromane and kleptomane (pyromaniac and kleptomaniac, respectively).
Apparently the word exists in English too, but I only know that because I went looking for it. I’ve never heard it used before. A melomaniac is described as a person (or dog!) that is abnormally affected by music or certain tones. The French don’t seem to use mélomane in such an extreme way. I saw it used in an advertisement for a Mother’s Day sale at a record store!
