怎樣看懂詞源字典裏的內容

faction (n.) c.1500, from M.Fr. faction (14c.) and directly from L. factionem (nom. factio) "political party, class of persons, " lit. " a making or doing, " from pp. stem of facere " to do" (see factitious). In ancient Rome, " one of the companies of contractors for the chariot races in the circus. " 翻譯如下： faction (名詞) 16世紀, 源自中古法語 faction (14世紀)，後者直接來自拉丁語的 factionem (主格為 factio)，表示 " political party, class of persons",該詞字面意思為 " a making or doing, " 由動詞facere " to do"的過去分詞詞幹衍生 (見詞條factitious)。在古羅馬該詞用來表示" one of the companies of contractors for the chariot races in the circus"。 註意到詞源字典在解釋詞源時，壹般采用逐級追溯來源的構架，即“faction源自中古法語的faction，faction源自拉丁語的factionem，factionem來自動詞facere的過去分詞”。
