abbot: [OE] Abbot comes ultimately from abbā, a Syriac word meaning ‘father’ (which itself achieved some currency in English, particularly in reminiscence of its biblical use: ‘And he said, Abba, father, all things are possible unto thee’, Mark 14:36). This came into Greek as abbás, and thence, via the Latin accusative abbatem, into Old English as abbud or abbod.

The French term abbé (which is much less specific in meaning than English abbot) comes from the same source. In much the same way as father is used in modern English for priests, abba was widely current in the East for referring to monks, and hence its eventual application to the head of a monastery. A derivative of Latin abbatem was abbatia, which has given English both abbacy [15] and (via Old French abbeie) abbey [13]. Abbess is of similar antiquity (Latin had abbatissa).
