Androgynous — having both masculine and feminine characteristics, or being distinctly neither — comes from Greek andro- (man) plus -gyne (woman) by way of Latin, on record since 1628. It’s day two of A.Word.A.Day’s “A change of character” week, illustrated by the Sleeping Hermaphrodite: an ancient marble copy of a lost Greek original, whose mattress and pillow were carved separately, by Bernini, in 1620 — eight years before this word entered English.
