Morphology

neomycin = mycin (opaque) = neo + mycin

'Mycin' is not a standalone English word with a transparent meaning, so the term is opaque for learners.

Etymology

Neomycin is made of neo- meaning 'new' and -mycin from a word for 'fungus' or a tiny organism that makes medicines. So neomycin is like a 'new' drug made by a microbe, which is why it is used as an antibiotic to fight infections.
