coral

en-noun

coral (countable and uncountable, plural corals)

From Old French coral (French corail), from Latin corallium, from Ancient Greek κοράλλιον (korállion, “coral”). Probably ultimately of Semitic origin, compare Hebrew גּוֹרָל (goral, “small pebble”), Arabic جَرَل (jaral, “small stone”), originally referring to the red variety found in the Mediterranean. Since ancient times, a common folk etymology, accepted by some earlier scholars, connected the word instead to Ancient Greek κόρη (kórē) (referring to Medusa). Beekes mentions both theories and considers the Semitic one convincing.

der

(countable) Any of many species of marine invertebrates in the class Anthozoa, most of which build hard calcium carbonate skeletons and form colonies, or a colony belonging to one of those species.

(uncountable) A hard substance made of the skeletons of these organisms.

Verrill.—The questions discussed in this paper were the position of the tabulate corals among Polyps, and the true value of the tabulate structure in classification. […] Prof. [Addison Emery] Verrill, therefore, concludes that the tabulate structure is of secondary importance as a character, in fixing their affinities, and that the Tabulata must be dismembered,—Halisites, Millepora, and their allies, being classed as Hydroids; and Pocillopora and Favosites with other extinct tabulated genera, as true Polyps.
