endeavor (n.) - 15世纪早期，"pains taken to attain an object"，字面含义 "in duty"，源自短语put (oneself) in dever "make it one's duty" (部分翻译古法语mettre en deveir "put in duty")，源自古法语dever "duty"，源自拉丁语debere "to owe"，最初表示 "keep something away from someone"，源自de- "away" (参看：de-) + habere "to have" (源自PIE词根*ghabh- "to give or receive")。One's endeavors meaning one's "utmost effort" 始于15世纪晚期。
