What does spiky mean?
Spiky is an adjective describing something that has, resembles, or is covered with sharp points. It is commonly used for hair that stands out in pointed directions, as well as for prickly plants, thorny fences, spiky leaves, and other pointed surfaces. The word gives a vivid impression of texture and shape, often suggesting something slightly dangerous, untidy, or uncomfortable to touch. In informal British English, spiky can also describe criticism or a subject that is difficult to discuss because it prompts sharp disagreement. In that figurative use, the word carries the idea of sensitivity and potential irritation rather than literal points. Spiky is especially useful when precision about texture or shape matters, while prickly and pointed can serve as less vivid alternatives. Its familiar, slightly playful sound also makes it effective in descriptions of hair, vegetation, and metaphorical character.
Having or resembling spikes; sharp-pointed or prickly.
"The path was lined with spiky bushes."
Often used for hair, vegetation, and barriers, but applicable to any distinctly pointed object.
Informally, sharply critical, contentious, or difficult.
"The proposal became a spiky issue at the meeting."
This figurative sense is especially associated with informal British English.
Spiky can turn an ordinary description of hair into a vivid picture—and can also make criticism sound uncomfortably sharp.

Where does spiky come from?
Spiky developed from the English noun spike with the adjective-forming suffix -y. Spike itself has long referred to sharp, projecting points, particularly on plants, barriers, or defensive structures. The derivative spiky therefore describes an object characterized by such points. The word is closely related to forms such as spike, spiked, and spikiness, while its figurative use developed from the physical sense of sharpness.
