=obdurate

ob- (against / all the way) + dur (to harden) + -ate (adj.) = hardened all the way through, hardened against everything. It takes the physical idea of hardness and applies it to a person's will or heart: an obdurate person has set like concrete, unmoved by any argument or plea.

Why It Means This

Obdurate is the most vivid member of the dur family because you can literally feel the metaphor: a heart or will turned to stone. The ob- intensifies it — not just hard, but hardened against you, set against giving in. It's a strong, formal word; calling someone obdurate is harsher than calling them 'stubborn.'
