establish: [14] Etymologically, to establish something is to ‘make it firm’. The word comes via Old French establir from Latin stabilīre, a derivative of stabilis ‘firm, secure’ (source of English stable and related to English stand). English originally acquired it at the end of the 13th century as stablish, but by the end of the 14th century the more ‘French’ spelling had been introduced, and gradually took over. => stable, stand[establish etymology, establish origin, 英语词源]
