protrude

/proʊˈtrud/

/prəʊˈtrud/

Other forms: protruding; protruded; protrudes

Protrude means to stick out. A gravestone protrudes from the ground, a shelf protrudes from a wall, a lollipop stick protrudes from your mouth.

From the Latin prō- "forward, out" + trūdere "to thrust," protrude often describes coastlines where rocks stick out into the water. Prō- gives us protrusion "something that sticks out," and protuberance "something that grows out of something else"––a goiter, for example, or a nose.
