Other forms: doughtiest; doughtier
Someone who's doughty is brave and determined, like a doughty knight who fearlessly rides off to slay a terrifying giant.
At first glance, you might confuse doughty with doughy, but the two words are quite different in meaning. Doughy things are soft and squishy, like unbaked bread. A doughty person is valiant and steadfast — like a doughty explorer who braves wild jungles and piranha-infested rivers in order to find the ruins of an ancient city. The word is derived from a root that means "strong."
