non-allergic

The word is a modern English formation built from established components. The prefix "non-" originates from Latin non, meaning "not," a straightforward negative particle. The base word "allergic" entered English in the early 20th century from German Allergie, which was coined from Greek elements allos (other, different) and ergon (work, activity) to describe a hypersensitive reaction. Therefore, "non-allergic" logically combines these parts to create a term meaning "not pertaining to such a hypersensitive reaction," precisely negating the condition described by its root.

Structure: non (not) + allergic (relating to allergy) - non: A prefix of Latin origin, meaning "not." It functions as a negative particle. - allergic: An adjective of English origin, derived from the noun 'allergy,' meaning having or relating to an allergy. It functions as the base word modified by the prefix.
