Did you know?

English has no shortage of words to describe stubbornness, and obstinate is one you might want to latch onto. It suggests an unreasonable persistence and is often used negatively to describe someone who is unwilling to change course or to give up a belief or plan. Animals can be obstinate, too—for instance, say, a beloved pet cat that refuses to get out of your easy chair when you want to sit down. Such an example makes a lot of sense with regard to obstinate’s history, too: the word traces back to a combination of the Latin prefix ob-, meaning “in the way,” and a word related to stare, meaning "to stand." But if you’re adamant about describing Whiskers’ stubborn behavior in more faunal terms, allow us to suggest bullheaded, dogged, or mulish.
