Abbé (from Latin abbas, in turn from Greek αββας = abbas father, from Aramaic abba) is the French word for abbot. It is the title for lower-ranking Catholic clergymen in France. A concordat passed between Pope Leo X and Francis I of France (between 1515 and 1521), gave the kings of France the right to nominate 255 Abbés commendataires for almost all French abbeys, who received income from a monastery without needing to render a service.[citation needed]
