Etymology

First attested in the 1450s as Middle English obdurat(e), borrowed from Latin obdūrātus ("hardened"), the perfect passive participle of obdūrō ("to harden"). The Latin joins the prefix ob- ("against") to dūrō ("to harden, render hard"), itself from dūrus ("hard"), and adds the adjective-forming suffix -ate; compare durable and endure.

From Latin obdūrātus, past participle of obdūrāre ("to harden, persist"), with the English verb formed by addition of the Latinate suffix -ate. The Latin root carries the sense of hardening against something — ob- ("against") and dūrus ("hard") — and entered English with that moral inflection already intact.
