pearl

Etymology

From Middle English perle, from Old French perle of uncertain etymology. Probably via unattested Medieval Latin *pernula, from Latin perna (“haunch; a marine bivalve shaped like a leg of lamb”) but also derived from Medieval Latin perla, from Latin perula (“little bag”). Its typographic use follows the name given by Jean Jannon to the type used in his miniature editions of Vergil, Horace, & the New Testament in the 1620s, which were the smallest printed works to his time. Its surfing use derives from the supposed resemblance to pearl diving.

noun

1. A shelly concretion, usually rounded, and having a brilliant luster, with varying tints, found in the mantle, or between the mantle and shell, of certain bivalve mollusks, especially in the pearl oysters and river mussels, and sometimes in certain univalves. It is usually due to a secretion of shelly substance around some irritating foreign particle. Its substance is the same as nacre, or mother-of-pearl. Round lustrous pearls are used in jewellery.
