obdurate in Context

"... even great careers must end sometime, and as often as not against obdurate wills." — Greg Baum, The Sydney Morning Herald, 17 Dec. 2025


Did You Know?

When trying to persuade someone who has an obdurate disposition, you may end up feeling rather dour about your ability to change their mind. To endure such encounters in the future, you may find that you need to be more durable and not let the person's mulishness get you down. Maybe you will find such situations less stressful if you can face them knowing that the words obdurate, dour, endure, and durable are etymological kissing cousins. All trace back to the Latin adjective durus, which means "hard."
