The GaulishethnonymAulerci is generally interpreted as meaning 'those who are far away from their traces' (tracks, paths), composed of the ablative prefix au- ('out of, away from') attached to the root lerg- ('trace', cf. MIr.lorg, OBret.lerg).[3][4][5]Pierre-Yves Lambert has also proposed a comparison with the Old Irishlerg ('slope, brink'), or with the Welsh/Bretonalarch ('swan').[6]
The relationship that linked the different tribes together remains uncertain. According to historian Venceslas Kruta, they could have been pagi that got separated from a larger ethnic group during the pre-Roman period.[1]
