Did You Know?

This term comes from polypous, a Greek word for "octopus", which meant literally "many-footed". To the untrained eye, the invertebrate known as the polyp may likewise appear to be many-footed, though it never walks anywhere since its "feet" are tentacles, used for stinging tiny organisms which the polyp then devours. The types of tumor known as polyps got their name because some seem to be attached to the surface by branching "foot"-like roots, even though most do not. Polyps of the nose or vocal cords are usually only inconvenient, causing breathing difficulty or hoarseness, and can be removed easily; however, polyps in the intestines can sometimes turn cancerous.

Origin and Etymology of polyp

French polype octopus, nasal polyp, from Old French polipe, from Latin polypus, from Greek polypous, from poly- + pous foot — more at foot


First Known Use: 1742
