Did you know?
If you're obstinate, you're just plain stubborn. Obstinate, dogged, stubborn, and mulish all mean that someone is unwilling to change course or give up a belief or plan. Obstinate suggests an unreasonable persistence; it's often a negative word. Dogged implies that someone goes after something without ever tiring or quitting; it can be more positive. Stubborn indicates a resistance to change, which may or may not be admirable. Someone who displays a really unreasonable degree of stubbornness could accurately be described as mulish.
