Having characteristics of both genders; neither distinctly male nor female, or relating to both sexes equally.
From Latin ambi- (both) + genus (gender, kind), with -al suffix. This is a rare technical term, more commonly replaced by unisex or androgynous in modern usage.
This word appears occasionally in older biological and anthropological texts, but modern English preferred androgynous from Greek—it's a good example of how Latin and Greek roots compete in scientific terminology.
