The act of giving someone a cognomen or additional name; the name itself that is conferred.
From Latin 'cognominatio,' derived from 'cognominare' (to give a cognomen), plus the English suffix '-tion' creating an abstract noun.
In ancient Rome, a cognomination could be either inherited (passed down through family) or earned (given as an honor for military victory or achievement), so your cognomen could literally tell your life story!
