Morphology
bacteriocin = bacterium (semi-transparent) = bacterio + cin + in
Learners can recognise 'bacteri(o)-' as relating to bacteria and '-in' as a protein suffix, so they can infer it's a bacterial protein, but the specialized meaning 'kills or inhibits other bacteria' is not predictable from morphology alone.
Etymology
The word bacteriocin starts with bacteria, meaning 'germs', and ends with a part like toxin, meaning 'poison'. So a helpful way to remember it is as a 'poison made by bacteria' that kills or stops other bacteria.
