chimera
UK: kɪˈmɪərə | US: kaɪˈmɪrə
n. 1. A mythical fire-breathing monster composed of disparate animal parts (e.g., lion, goat, serpent).
n. 2. An unrealistic or fantastical idea or creation.
n. 3. (Genetics) An organism containing genetically distinct tissues (e.g., from fusion of embryos).
The word traces back to Greek mythology’s Khimaera, a composite beast slain by Bellerophon. Its name reflects its hybrid anatomy (goat-lion-serpent). Latin adopted it as chimaera, later entering English as "chimera." The modern sense of "illusion" or "genetic hybrid" evolved metaphorically from the myth.
