“The formal title of custos (or occasionally conservator) placitorum corone continued to be used throughout the Middle Ages, but the more convenient shorter forms coronarius, which was confined to a short period around 1200, and CORONATOR rapidly gained greater currency. The English form was ‘coroner’ or ‘crowner.’ ” R.F. Hunnisett, The Medieval Coroner 1 n.1 (1961).
