Root Explanation

Allergin is derived from the Greek word 'allos' (meaning other) and 'ergon' (meaning work or activity). The term originally referred to a reaction or response to something that is perceived as foreign or different, hence the concept of an allergy being a reaction to an 'other' substance.

Memory Tip

Think of 'other' ('allos') and 'work' ('ergon') to remember that 'allergin' refers to a reaction to something that is different or foreign.
