(pronounced AHB-duh-rut)

Try to remember this word by thinking of another word: objection. This adjective means persistently determined to do wrong and annoy, as well as dead set against to anyone else’s point of view. Think stubborn mule.

Example: Although Anna tried extremely hard to convince Vincent to come up with an alternate site plan to present at the following week’s development meeting, he remained obdurate in stance that his plan was the only option.
