- pothole (n.)
[pothole 词源字典]
- also pot-hole, 1826, originally a geological feature in glaciers and gravel beds, from Middle English pot "a deep hole for a mine, or from peat-digging" (late 14c.), now generally obsolete, but preserved in Scotland and northern England dialect; perhaps ultimately related to pot (n.1) on notion of "deep, cylindrical shape." Applied to a hole in a road from 1909.[pothole etymology, pothole origin, 英语词源]
