protuberance

The word 'protuberance' originates from the latin verb 'prōtūberāre', meaning 'to swell out'. This verb is itself a compound of the prefix 'prō-' ('forward, forth') and 'tūber' ('a swelling, bump'). The core concept is of something bulging or pushing itself forward from a surface. The latin noun 'prōtūberantia' described the state of swelling out, which entered english in the 17th century as 'protuberance'. Thus, the modern term retains the literal, physical sense of its components: a forward-projecting swelling, elegantly capturing the image of a distinct, rounded lump extending from a plane.
