Since several posts on this thread focus on Scots vocabulary, let me see if I can find the small glossary which I see appended to "Sleep Weel My Bairnie" at sites like "rampant Scotland." I don't know whom to credit for this glossary. Sorry, I would prefer to give credit where due.

munelicht brae = moonlit hillside

her lane       = alone

ayont          = beyond

bour-tree      = elder tree

shaw          = flat ground at the foot of a hill
                [what? no mention of trees?]
