Why “sleiveen” is a great word
SLEIVEEN — [Noun] A sly trickster, particularly one whose cunning is of rustic, unsophisticated origin. From Irish slíghbhín or slíbhín, with the same meaning, derived from sliabh ("mountain"), branding its bearer with the mark of the hinterlands. Unlike a "charlatan," who cloaks deceit in false expertise, or a "scoundrel," a blunt label for any villain, a sleiveen traffics in a quieter, homespun deception. He is the man at the fair who palms the shaved die; the neighbor whose shrewd land swap leaves you with a barren acre; the whisper in the pub that turns a community's goodwill to mistrust. It is the quiet treachery of the familiar landscape, where deceit is an old craft honed in the lonely, watchful hills.
