Etymology: "Canniest" is the superlative of "canny," and the adjective's roots lie in a verb meaning "to know how to." Its ancestor is Old English "cunnan," meaning "to know how to, be able to," which is also behind modern "can." In Middle English the first-person and third-person singular form "can" was used to mean "to know," and northern English dialect took that verb and added the suffix "-y," producing a word meaning knowing, shrewd, or capable. Scots adopted a parallel form, and the adjective still carries that northern, down-to-earth flavour. The word's sense of careful caution, the "canny" that means prudent or wary, grows from the same root, so a person described as canny is someone who knows what they are doing and how to protect their own interests. Readers may also meet "canny" in the sense of "considerable" or "pleasant," as in a "canny bit" of money, which is a regional extension of the same core idea of competence.
