Etymology

Origin of pebble

First recorded in 1250–1300; Middle English pibbil, puble, pobble; compare Old English pæbbel (in placenames), papel-, popel- (in compounds); phonological relations unclear

Explanation

Pebbles are the small, round stones you might find on a beach. If you want a pet rock, a smooth pebble would be a good choice. A pebble beach might not be quite as soft underfoot as a sandy one, but pebbles tend to be smooth and rounded — unlike jagged-edged rocks. A beach covered with smooth pebbles is known as a "shingle beach." The origin of the word pebble is a mystery, although some suspect a connection to the Latin papula, "pustule, pimple, or swelling."
