This etymology vividly illustrates the concept of a protuberance as a noticeable or prominent bulge, projection, or swelling that extends outward from a surface. It conveys the idea of something pushing forward and swelling out, creating a conspicuous and distinct feature on an otherwise flat or uniform surface. Thus, the word 'protuberance' reflects its Latin origins by emphasizing the characteristic of standing out or protruding prominently.
