connection

Etymology

From Middle English conneccioun, connexioun, conneccyon, conneccion, from Latin connexionem (nominative connexio (“a conclusion, binding together”)), from connectō, an alternative spelling of cōnectō (“I bind together”), from compound of co- (“together”) and nectō (“I bind”). In American English mid-18c., spelling shifted from connexion to connection (equivalent to connect + -ion), thus making connexion British dated and connection in international use.
