Etymology

The word "spiky" derives from "spike" (Old English spīc, meaning "sharp point" or "nail"), combined with the adjectival suffix "-y," which indicates "having the quality of." The root "spike" traces back to Proto-Germanic spīkaz, related to piercing or pointed objects. Over time, "spiky" evolved to describe both literal sharpness (e.g., spiky plants) and figurative traits (e.g., a spiky personality).
