单词 quintillion
释义

quintillionn.adj.

Brit. /kwɪnˈtɪljən/, U.S. /kwɪnˈtɪljən/
Forms: 1600s quintilion, 1600s– quintillion.
Origin: A borrowing from French. Etymon: French quintillion.
Etymology: < French quintillion a thousand quadrillions (1027), a million quadrillions (1030) (1630 as quintillon ) < classical Latin quīntus fifth (see quint n.1) + -illion (in million million adj.). Compare billion n., trillion n., etc.
A. n.
Originally: the cardinal number equal to the fifth power of a million, represented by 1 followed by thirty zeros (1030) (now chiefly British). Later also (originally U.S.): the cardinal number equal to the sixth power of a thousand, or 1 followed by eighteen zeros (1018). Also hyperbolically: an unspecified but very large number or amount.The displacement of the original sense by the later one is similar to that described for billion (see billion n.).
