NOTE 1: The earlier forms for nominative and accusative were -os, -om, and these were always retained after u and v up to the end fo the Republic. The terminations s and m are sometimes omitted in inscriptions: as, Cornélio for Cornélios, Cornéliom.
NOTE 2: Stems in quo-, like equo-, change qu to c before u. Thus, - ecus (earlier equos), equí, equó, ecum (earlier equom), eque. Modern editions disregard this principle.
