mosque: [17] Mosque means etymologically a place where you ‘bow down’ in prayer and is, not surprisingly, of Arabic origin. It comes from Arabic masjid ‘place of worship’, a derivative of the verb sajada ‘bow down’. English acquired the word via Italian moschea and French mosquée as mosquee, but soon dropped the final -e. (The Arabic form masjid or musjid has been intermittently used in English in the 19th and 20th centuries.) [mosque etymology, mosque origin, 英语词源]
