the word "claymore"

[An t-Ileach]

I have only the smallest understanding of the Gaelic language but I have heard it pronounced more like 'clay-eww moor' and 'clay-eww da liv' but it certinaly could be an accent thing, inccorect source or fuzzy memory...

It's probably dialect variation; there's some distinct variations between Argyll and the southern islands, the northern islands, and the mainland up to Inverness.

Thanks for clearing up that thing about the dirk.
