Origin of: Worm turns

Worm turns

The worm turns means that even the weak will do their utmost to reverse a previously adverse situation. The old proverb, from at least the 1500s, is “tread on a worm and it will turn” and Shakespeare picked up on it in Henry VI Part II (1591) Act II, Scene II. “The smallest worm will turn being trodden on.”
