bogle

“Castle Craig,” this bogle of a railway employee repeated laconically.

From "Code Name Verity" by Elizabeth Wein

Ghaist nor bogle shall thou fear; Ghost, goblin Thou'rt to Love and Heaven sae dear, Nocht of ill may come thee near, Nought My bonnie dearie.

From Robert Burns How To Know Him by William Allan Neilson

These oppressed yet dreaded fugitives obtained, naturally enough, the character of the German spirits called Kobold, from which the English goblin and the Scottish bogle, by some inversion and alteration of pronunciation, are evidently derived.

From Letters on Demonology and Witchcraft by Sir Walter Scott

In this pious design the bogle was happily frustrated by the intervention of some trees which grew on the precipice, and to which my unhappy grand-uncle clung with the zeal of a drowning man. 

From Folk-Lore and Legends Scotland by Anonymous

I’m no bogle, but you’d better not ask what I am.

From Bluebeard by Clifton Johnson
