The word 'chimaera' derives from Ancient Greek khimaira (Χίμαιρα), which originally meant 'she-goat' — specifically a young female goat, a yearling one winter old. In Homer's Iliad (Book VI), the Chimaera appears as a monstrous fire-breathing creature with the head of a lion, the body of a goat, and the tail of a serpent, slain by the hero Bellerophon astride the winged horse Pegasus.

Chimera and Himalaya are etymological cousins. Both descend from PIE *ǵʰey- ('winter/snow') — Greek took it as kheima ('winter'), naming a young goat by its first survived winter, which then became a fire-breathing monster; Sanskrit took it as himá ('snow'), naming the highest mountain range on Earth.

The underlying PIE root is *ǵʰey-, meaning 'winter' or 'snow', reflecting the pastoral logic that a khimaira was a 'yearling' — an animal one winter old. This same root produced Latin hiems ('winter'), the adjective hiemalis/hiemal ('of winter'), and the verb hibernare ('to spend the winter'), giving English 'hibernate'. The Greek kheima ('winter weather, storm') and kheimon ('winter') are direct cognates from the same root, preserving the original seasonal meaning that the mythological monster's name had long since obscured. Key roots: *ǵʰey- (Proto-Indo-European: "winter, snow, cold season"), χίμαιρα (khimaira) (Ancient Greek: "she-goat, yearling (one winter old)"), chimaera (Latin: "the mythological fire-breathing monster; a wild fancy").
