🌳Etymology
Origin
The term was coined in 1906 by German physician Clemens von Pirquet, combining Greek 'allos' (other, different) and 'ergon' (action, work) to create 'allergen,' literally meaning 'that which produces an altered reaction.' It describes a substance that triggers an abnormal immune response in the body.
Breakdown
allo- (Greek 'allos': other, different) + -erg- (Greek 'ergon': action, work) + -en (agent noun suffix: substance or thing that produces an action).
