gillie
A male attendant of a Scottish Highland chief.
But my good companion had nothing in his mind but kindness; and the next moment, two of the gillies had me by the arms, and I began to be carried forward with great swiftness (or so it appeared to me, although I dare say it was slowly enough in truth), through a labyrinth of dreary glens and hollows and into the heart of that dismal mountain of Ben Alder.
A fishing and hunting guide; a man or boy who attends to a person who is fishing or hunting, especially in Scotland.
Every deerstalker will bear witness to the eagerness of Highlanders in pursuit of their old favourite game, the dun deer; the mountaineer shews what he is when his eye kindles and his nostril dilates at the sight of a noble stag; when the gillie forgets his master in his keenness, and the southern lags behind; when it is "bellows to mend" and London dinners are remembered with regret.
Where it comes from
From Scottish Gaelic gille (“helper”), from Middle Irish gilla (“youth, young man; boy, male child; messenger, page, servant”), possibly borrowed from Old Norse gildr (“brawny, stout; of full worth”). Compare Irish giolla (“boy”).
