Obs.–0 [expl. as f. ab away + ann-us year; but evidently n. of action f. med. Lat. abannīre (cf. Fr. bannir and Eng. abann) to banish.] ‘A Banishment for one or two years for manslaughter.’ J. from Blount, Glossogr., 1656, and Bailey, 1721. So abannatio in Du Cange, but evidently a mere guess from a false etymology, the meaning being simply ‘banishment.’
1656. Blount, Glossogr., Abannition, a banishing for a year, properly among the Greeks, for man-slaughter.
