Surface Forms

antihistamine singular

Morphology

antihistamine = histamine (transparent) = anti + histamine

The meaning is directly built from 'anti-' plus 'histamine', referring to something that counters histamine.

Etymology

Antihistamine comes from two parts, anti- and histamine, where anti- means 'against', just like in antibiotic, and histamine is the body chemical that makes you sneeze and itch. So an antihistamine is a medicine that works 'against' that chemical to reduce allergy symptoms.
