公元前1200年, professioun,指“進入宗教團體時所作的誓言”,源自於12世紀的古法語 profession,直接源自拉丁語 professionem(主格 professio),“公開聲明”,動作名詞,來自 profiteri 的過去分詞詞幹“公開宣佈”(參見 profess)。
“任何莊嚴的聲明”的意思來自於14世紀中期。指“一個人聲稱自己擅長的職業,一個職業”是從15世紀初開始的; 指“從事某種職業的人羣”是從1610年開始的; 作爲“賣淫”的委婉說法(比較 oldest profession)是從1888年開始記錄的。
Formerly theology, law, and medicine were specifically known as the professions; but, as the applications of science and learning are extended to other departments of affairs, other vocations also receive the name. The word implies professed attainments in special knowledge, as distinguished from mere skill; a practical dealing with affairs, as distinguished from mere study or investigation; and an application of such knowledge to uses for others as a vocation, as distinguished from its pursuit for one's own purposes. In professions strictly so called a preliminary examination as to qualifications is usually demanded by law or usage, and a license or other official authority founded thereon required. [Century Dictionary]
以前神學、法律和醫學被特別稱爲 the professions; 但是,隨着科學和學習的應用擴展到其他部門的事務,其他職業也得到了這個名稱。這個詞意味着在特定知識方面的公開承認,與純粹的技能相區別; 與純粹的研究或調查相區別的實際事務處理; 以及將這種知識應用於爲他人謀生的職業,與爲自己的目的而追求相區別。在嚴格意義上的職業中,通常根據法律或慣例要求進行資格的初步考試,並要求獲得基於此的許可證或其他官方授權。[世紀詞典]
