can‧ny, adj. /ˈkæni/

Indicating extreme cleverness, a metaphorical construction from “canyon.” Originally referred to general knowledge before usage narrowed its definition – specifically, having knowledge as deep as a canyon.

The path from the etymology of “canny” to that of “uncanny” (“strange, mysteriously unsettling”) is extremely complex, and not recommended for those with a bibliorienteering rank less than 7.
