prickly

the word prickly is a native english formation, built upon the old english root prica, which denoted a small point or puncture. this root is part of the wider germanic family, related to the dutch prik and the german prickeln, all conveying a sense of sharp, pointed stimulation. the adjectival suffix -ly, from old english -lic, was added to mean "having the nature of," transforming the noun into a descriptor. thus, prickly literally means "full of or resembling sharp points," a concrete meaning that extended metaphorically to describe both physical sensations like tingling and personality traits marked by irritability.

Structure: prick (sharp point) + ly (adjective-forming suffix) prick (old english prica, meaning a point, dot, or puncture; functions as the core root denoting sharpness). ly (old english -lic, from germanic -līko-, meaning "having the qualities of"; functions as an adjectival suffix).
