Attested: Ptolemy 2,3,1 Λογγου river mouth; RC Longis
Where: Loch Linnhe according to R&S and Marx (2013), a long sea loch that leads up to Fort William and the Great Glen, rather than the modern Loch Long on the north side of the Clyde.
Name Origin: This name probably just referred to the length of this sea inlet, but it might also have referred to a site of ship building or repairing, because Latin longus ‘long, distant’ gave rise to navis longa ‘long ship’, the usual Roman name for a warship, and also to Old Irish long ‘ship’.
Notes: The name may survive in Luing and Lunga, names of two islands in the loch, which are candidates to be RC’s Longis, which is listed as if it was an island.
