Borralaidh,
is
from the old Norse Borghlid, fort slope.
The place name ‘Borralie’ may
derive from the Old Norse
borg-
for houses clustered around a fort or
monastic site and -ley,
probably the plural of meadow (Johnston 1934, 12; Darwood 1995). The
name most likely refers to a dun (site 123 in Lelong & MacGregor
2003) which is perched on a small headland overlooking the loch,
around which cluster later, eighteenth-century township buildings.
