exileyoudaoicibaDictYouDict[exile 词源字典]
exile: [13] Latin exul meant ‘banished person’. This was formed from the prefix ex- ‘out’ and a prehistoric Indo-European base *ul- ‘go’ (represented also in Latin ambulāre ‘walk’, source of English amble and ambulance). From it was created the noun exilium ‘banishment’, which in Old French became essil. This was subsequently remodelled to exil, on the basis of its Latin source, and passed on to English.

c. 1300, from Old French essillier "exile, banish, expel, drive off" (12c.), from Late Latin exilare/exsilare, from Latin exilium/exsilium "banishment, exile; place of exile," from exul "banished person," from ex- "away" (see ex-) + PIE root *al- (2) "to wander" (cognates: Greek alaomai "to wander, stray, or roam about").

c. 1300, "forced removal from one's country," from Old French exil, essil (12c.), from Latin exilium "banishment; place of exile" (see exile (v.)). From c. 1300 as "a banished person," from Latin exsul, exul.
Several etymologies are possible. It might be a derivative of a verb *ex-sulere 'to take out' to the root *selh- 'to take', cf. consul and consulere; hence exsul 'the one who is taken out'. It might belong to amb-ulare *-al- 'to walk', hence 'who walks out'. It might even belong to *helh-, the root of [Greek elauno] 'to drive': ex-ul 'who is driven out' [de Vaan, "Etymological Dictionary of Latin and the other Italic Languages"]
