The quality or state of being arrogant; excessive pride or self-importance.
From Old French 'arrogance,' derived from Latin 'arrogantia,' from 'arrogans' meaning claiming for oneself excessively. The suffix '-cy' creates abstract nouns denoting states or qualities.
Medieval writers loved 'arrogancy'—it sounded more dramatic and serious than simple 'arrogance,' which is why you see it in Shakespeare and older texts warning against the sin of pride that leads to a character's downfall.
