Surface Forms

interferon singular
interferons plural

Morphology

interferon = interfere (semi-transparent) = interfere + on

Formed from the verb 'interfere' plus the specialized noun-forming suffix '-on'; the connection to 'something that interferes' is clear but the protein/technical sense requires scientific knowledge.

Etymology

Interferon comes from the verb interfere, which means 'to come between', plus the protein ending -on. A helpful image is that interferon 'comes between' viruses and healthy cells to stop the virus from copying, so it is a protein cells make to fight infection.
