What does prickly mean?
Prickly describes something covered with small sharp points and, figuratively, a person who is easily irritated or quick to take offence. Its literal sense is especially familiar from thorny plants, spiny fruit, and prickly skin, while phrases such as “prickly pear” have become standard names rather than unusual descriptions. The figurative sense is often used for behaviour that appears defensive, impatient, or overly sensitive. “He was prickly about the change” suggests that the subject reacted sharply to discussion or criticism, whereas “a prickly personality” presents irritability as a more established trait. Although the two meanings are distinct, they share an image of sharpness. Prickly is useful because it efficiently communicates both a physical quality and a guarded, sometimes defensive temperament without requiring extensive explanation.

Where does prickly come from?
Prickly was formed in English from the element prick and the suffix -ly. Its source goes back to Middle English prick and ultimately Old English prica, associated with a point or pricking; the closely related prickle developed from the same Germanic root. The figurative sense for an irritable or sharp-tempered person developed by the early modern period from the idea of being sharp in manner.
