polyp
UK: ˈpɒlɪp | US: ˈpɑːlɪp
n. 1. A small, simple aquatic animal with a tubular body and a mouth surrounded by tentacles (e.g., coral polyps).
n. 2. A growth projecting from a mucous membrane, often found in the nose, colon, or uterus (medical term).
The word "polyp" originates from Greek polypous (πολύπους), combining poly- (many) and -pous (foot), referring to the tentacles of the organism resembling "many feet." The medical sense emerged later, likening abnormal growths to the tentacled form of the aquatic polyp. The morpheme p here is a shortened form of the Greek pous, preserved in English spelling.
