travail（n.）
“劳动，辛苦”，公元13世纪中叶，源自古法语 travail “工作，劳动，辛苦，痛苦的努力，麻烦； 艰苦的旅程”（12世纪），来自 travailler “劳动，辛苦”，最初的意思是“麻烦，折磨，折磨”，源自于通俗拉丁语 *tripaliare “折磨”，来自于拉丁语 *tripalium（在晚期拉丁语中为 trepalium）“酷刑工具”，可能来自于拉丁语 tripalis “有三根桩”（来自于 tria “三”； 参见 three + palus “桩”（来自于 PIE *pakslo-，是词根 *pag- “固定”的带后缀形式），听起来很不祥，但确切的概念是模糊的。动词记录于公元13世纪后期的英语中，源自于古法语中的动词。

travail（v.）
late 13c., travailen, "take pains, suffer pains," from Old French travailler "to toil, labor," originally "to trouble, torture, torment," from Vulgar Latin *tripaliare "to torture," from *tripalium (in Late Latin trepalium) "instrument of torture," which is said to be probably from Latin tripalis "having three stakes" (from tria "three;" see three + palus "stake" (from suffixed form of PIE root *pag- "to fasten"), darkly suggestive, but the exact notion is obscure.
In English by mid-14c. specifically as "suffer the pangs of childbirth, be in labor;" in Middle English also "labor in the service of God; work for wages." Related: Travailed; travailing.
