Let me work with what's clearly supportable: - monomeric (English) comes from monomer (English) - monomer comes from mono- + -mer - -mer comes from Ancient Greek μέρος (meros, "part") However, the chain then jumps to χρῶμα (chroma, "color") and Proto-Indo-European -kos, which don't connect logically to the monomer pathway. Given the rules require me to state only what the chain supports and not invent steps, and this chain appears malformed, I should flag this rather than fabricate
