Etymology: The word is a chain of three pieces. "Cephalosporium" is the name of a genus of fungi, and it comes from Greek "kephalē", "head", plus "sporā", "seed" or "spore", because the fungus produces spores in head-like clusters. The "-in" in "cephalosporin" is the suffix chemists use for antibiotic and other drug-type substances, and it was the fungus-derived antibiotic cephalosporin that gave the family its name. "Cephalosporanic" builds on that name by adding the adjective ending "-ic", which in English descends from Latin "-icus" and was used to form adjectives meaning "pertaining to". The chemical sense is precise: cephalosporanic acid is the core ring structure, and the medicines are modified versions of it. So the word describes a chemical framework rather than the fungus itself.
