Root Explanation

Allergenic → It is formed from "allergen" (from Greek "allos" meaning other and "genes" meaning produced by) and the suffix "-ic" (meaning pertaining to). The word "allergenic" refers to something that is related to or causes an allergic reaction.

Memory Tip

Think of something that is 'produced by' ('genes') and causes a reaction that is 'other' ('allos') — that's why allergenic means related to allergens.
