- normalcy (n.)
[normalcy 词源字典]
- 1857, "mathematical condition of being at right angles," from normal + -cy. Associated since c. 1920 with U.S. president Warren G. Harding and derided as an example of his incompetent speaking style. Previously used mostly in the mathematical sense. The word prefered by purists for "a normal situation" is normality (1849).[normalcy etymology, normalcy origin, 英语词源]
