Etymology

The meaning of the name ''Aln'' is uncertain, but it is generally seen as a river-name of the '' Alaunos'' or ''Alaunā''. Names of this type could derive from the Celtic root *''al''- ('feed, raise, nurture') or *''alǝ''- (to wander'), or else from the Brittonic element ''*al-'', "shining, bright" (

Welsh Welsh may refer to: Related to Wales * Welsh, referring or related to Wales * Welsh language, a Brittonic Celtic language spoken in Wales * Welsh people People * Welsh (surname) * Sometimes used as a synonym for the ancient Britons (Celtic peopl ...

''alaw'', 'waterlilly'). Another suggestion is that the name is derived from the Brittonic root ''*Alaun-'' (‘holy one’ or ‘mighty one’).

, a 2nd Century AD Roman cartographer. He refers to it as the River Alaunos or Alaunus (Geographica 2.3.4.18), on which seems to be situated the town of Alauna (Geographica 2.3.7.6). This can speculatively be identified as the Roman fort at Learchild, where the Devil's Causeway crosses the river. The Aln is a relatively small river but has been important through history as one of the boundaries along which English and Scottish troops marching to war had to cross; for that reason, it was at times heavily defended. For example, the river flows past Learchild Roman Fort and, more significantly,
