Etymology: "Protuberating" is the present participle of "protuberate", which comes from Late Latin "prōtuberō", meaning to swell or bulge out. The Latin verb is built from "pro-", forward or outward, and "tuber", a swelling or lump, so the core idea is something pushing out beyond its surroundings. The same root gives English "protuberant" and "protuberance", both describing things that stick out from a surface, such as a bony knob or a swelling on the body. "Tuber" itself, in the sense of a rounded swollen root or stem like a potato, shares this bulging sense. The verb "protuberate" is a rarer form, and its participle carries the meaning of something actively rising or projecting from where it began.
