Origin
From Latin obstinatus (resolved, stubborn), past participle of obstinare (to persist), from ob- (against) and a root related to standing firm.
History
Obstinate has long described people who will not yield. It can apply to problems and conditions too: an obstinate stain, an obstinate fever. Praise is rare; the tone usually leans critical. Still, history keeps room for obstinate courage when the stand is justified.
