Cunning

n. The faculty that distinguishes a weak animal or person from a strong one. It brings its possessor much mental satisfaction and great material adversity. An Italian proverb says: "The furrier gets the skins of more foxes than asses."

cunning , meaning “artful,” and by extension “innocently artful,” and hence “bright,” “amusing,” or “characterized by quaint and playful moods,” is often improperly introduced to imply “dainty,” “choice,” especially if applied to anything diminutive. Such usage is not permissible. A kitten may properly be said to be cunning, but not a brooch, although (in archaic usage) that may exhibit the cunning or skill of the artificer.
