patrolyoudaoicibaDictYouDict[patrol 词源字典]
patrol: [17] What is now a reasonably dignified term began life as a colloquialism meaning ‘paddle about in mud’. English acquired the word via German from French patrouiller, which originally denoted ‘tramp around through the mud of a military camp – when doing guard duty, for instance’. This was an alteration of Old French patouiller ‘walk or trample in mud’, a verb based on the noun patte ‘paw’.

Other English words which trace their history back to patte are patois [17] (which developed via the Old French verb patoier ‘trample on’, hence ‘treat roughly’, and originally meant ‘rough speech’) and patten ‘wooden shoe’ [14].

catastrophe (n.)youdaoicibaDictYouDict
1530s, "reversal of what is expected" (especially a fatal turning point in a drama), from Latin catastropha, from Greek katastrophe "an overturning; a sudden end," from katastrephein "to overturn, turn down, trample on; to come to an end," from kata "down" (see cata-) + strephein "turn" (see strophe). Extension to "sudden disaster" is first recorded 1748.
foil (v.1)youdaoicibaDictYouDict
c. 1300, foilen "to spoil a trace or scent by running over it" (more commonly defoilen), irregularly from Old French foler, fuler "trample on, injure, maim; ill-treat, deceive, get the better of" (13c., Modern French fouler), from Vulgar Latin *fullare "to clean cloth" (by treading on it), from Latin fullo "one who cleans cloth, a fuller," which is of unknown origin. Compare full (v.).

Hence, "to overthrow, defeat" (1540s; as a noun in this sense from late 15c.); "frustrate the efforts of" (1560s). Related: Foiled; foiling. Foiled again! as a cry of defeat and dismay is from at least 1847.
full (v.)youdaoicibaDictYouDict
"to tread or beat cloth to cleanse or thicken it," late 14c., from Old French foler, fouler "trample on, press," from Latin fullo "fuller, launderer," also a kind of beetle, a word of unknown etymology. Perhaps the Middle English word was from Old English agent-noun fullere, which probably was formed from Latin fullo with a native ending.
