What does spinose mean?
Spinose is a formal adjective meaning covered with, bearing, or having spines. It is especially common in botanical and zoological descriptions: a plant may have spinose leaves, stems, or bristles, while an animal may possess a spinose body covering. The word suggests a sharp, protective quality and therefore conveys the idea of natural armor. Although it can occasionally be used figuratively for an argumentative or difficult subject, such usage is less frequent and more literary than the technical biological sense. In general writing, spiny or thorny often provides a clearer alternative. Spinose is particularly useful in precise descriptions of morphology because it specifically identifies the presence of spines rather than merely an uneven or rough surface.

Its Latin relatives include spinal, spinous, and spinule, all of which continue to reflect the same ancient word for a spine or thorn.
