amber (n.)youdaoicibaDictYouDict
mid-14c., "ambergris, perfume made from ambergris," from Old French ambre, from Medieval Latin ambar "ambergris," from Arabic 'anbar "ambergris." In Europe, the sense was extended, inexplicably, to fossil resins from the Baltic (late 13c. in Anglo-Latin; c. 1400 in English), which has become the main sense as the use of ambergris has waned. This formerly was known as white or yellow amber to distinguish it from ambergris, which word entered English early 15c. from French, which distinguished the two substances as ambre gris and amber jaune. The classical word for Baltic amber was electrum (compare electric).
ambergris (n.)youdaoicibaDictYouDict
early 15c., from Middle French ambre gris "gray amber" (see amber), "a wax-like substance of ashy colour, found floating in tropical seas, a morbid secretion from the intestines of the sperm-whale. Used in perfumery, and formerly in cookery" [OED]. Its origin was a mystery in Johnson's day, and he records nine different theories. King Charles II's favorite dish was said to be eggs and ambergris [Macauley, "History of England"]. French gris is from Frankish *gris or some other Germanic source (cognates: Dutch grijs, Old High German gris; see gray (adj.)).
Praise is like ambergris; a little whiff of it, by snatches, is very agreeable; but when a man holds a whole lump of it to his nose, it is a stink and strikes you down. [Pope, c. 1720]
