Morphology

allergen = allergy (transparent) = allergy + gen

Formed from the noun 'allergy' plus the productive suffix '-gen' meaning 'that which produces or causes,' so the word denotes something that causes an allergic reaction.

Etymology

Allergen comes from Greek parts allo- meaning 'other' and -gen meaning 'to produce', like in generate. So an allergen is something that 'produces' a different reaction in some people, in other words a thing that causes an allergic reaction.
