Origin

It comes from Ancient Greek ἱεραρχία (hierarkhía, 'rule of a high priest'), from ἱεράρχης ('high priest'), itself from ἱερός ('holy') plus ἄρχω ('I rule'). The word passed through Latin and Old French into Middle English, and the H was re-added around 1500 under the influence of Classical Latin.
