Pustulate

Part of speech: adjective, verb

Definitions

1. To develop or cause to develop inflammation characterized by the formation of pus-filled blisters or lesions on the skin or tissue; to become covered with or produce pustules indicating infection or irritation
2. To undergo a process resulting in raised, pus-containing bumps on a surface, often due to infection or inflammatory conditions; to manifest signs of pus accumulation in affected areas
3. To form or exhibit pustules, which are small, inflamed elevations on the skin filled with pus; to show signs of an infective or eruptive condition involving pustular eruptions or swellings

Etymology: Pustulate comes from the Latin "pustulatus," the past participle of "pustulare," meaning "to blister." The Latin verb was built on "pustula," a blister or pimple, so the word's core idea is a raised swelling on the skin. That physical image carried into English as a description of anything studded with such eruptions. The adjective sense, covered with pus, narrows that broader idea to the fluid itself. Because the word came into English through a learned Latin route rather than everyday speech, it reads as technical, and it is most often met in medical and botanical descriptions. Its verb form is built on the same participle and keeps the same blistering sense.
