barbed

the word "barbed" originates from the latin barba, meaning "beard". the semantic extension from "beard" to a "sharp, backward-pointing projection" likely arose from the visual similarity of a fishhook's point or an arrowhead's jagged edge to a rough beard. this sense of a hooked point gave rise to the english noun "barb". by adding the adjectival suffix "-ed", meaning "having the qualities of", the word "barbed" was formed to describe something furnished with barbs. the figurative meaning, describing a cutting or pointed remark, is a natural metaphorical extension from the physical sharpness of a barb to the psychological sting of critical language.

Structure: barb (sharp point) + ed (adjective suffix) barb (from latin barba meaning "beard", later "a beard-like projection, hook"); ed (from old english -ed, -od, -ad, a suffix forming adjectives from nouns or verbs, meaning "having, provided with").
