effort

将“effort”与“eff”关联记忆，想象一个“eff”在努力（"force"的缩写）地工作，形成“effort”。这个“eff”就像一个小人物在努力奋斗，帮助记忆单词的含义。

effort 努力

ef-, 向外。-fort, 力量，词源同fort, fortify.

effort

effort: [15] Etymologically, effort is the ‘putting out’ or ‘showing’ of ‘force’. It comes ultimately from Vulgar Latin *exfortiāre, a compound verb formed from the prefix ex- ‘out’ and the adjective fortis ‘strong’. This passed into Old French as esforcier ‘force, exert’, from which was derived the noun esforz. English borrowed it in its later form effort.
=> force

effort (n.)

late 15c., "laborious attempt, strenuous exertion," from Middle French effort, from Old French esforz "force, impetuosity, strength, power," verbal noun from esforcier "force out, exert oneself," from Vulgar Latin *exfortiare "to show strength" (source of Italian sforza), from Latin ex- "out" (see ex-) + Latin fortis "strong" (see fort).

Effort is only effort when it begins to hurt. [Ortega y Gasset, 1949]

Related: Efforts "voluntary exertion," also "result of exertion."
