Obdurate

OB-dur-it

Definition

(adjective) Stubbornly refusing to change one’s opinion or course of action; hardened against moral influence.

Example

Despite overwhelming evidence, he remained obdurate in his denial of wrongdoing.

Word Origin

Late Middle English: from Latin “obduratus,” past participle of “obdurare,” from “ob-” (in opposition) + “durare” meaning “to harden,” from “durus” meaning “hard.”

Fun Fact

Obdurate literally means “hardened against,” suggesting someone who has deliberately calcified their position beyond mere stubbornness. The word appears frequently in religious contexts describing hearts hardened against grace or compassion—Pharaoh’s obdurate heart in biblical narratives exemplifies willful resistance to moral persuasion. Unlike simple stubbornness, obduracy implies active resistance rather than passive inflexibility. Legal scholars describe obdurate defendants who refuse plea deals despite overwhelming evidence. The word shares roots with “durable” and “endurance,” but where those suggest positive persistence, obduracy is persistence in wrongness. Charles Dickens loved “obdurate” for describing misers and villains immune to sympathy. Modern psychology might diagnose severe obduracy as pathological rigidity, though sometimes standing obdurate against popular opinion requires courage rather than indicating vice.

Vacuous

VAK-yoo-us

Definition

(adjective) Devoid of intelligence, substance, or meaningful content; empty in a way that is made worse by the appearance of fullness.

Example

The panel discussion was so vacuous — four articulate people saying nothing of substance for ninety minutes — that the audience left feeling vaguely cheated by their own attention.

Word Origin

Vacuous derives from the Latin vacuus, meaning “empty” or “void,” rooted in vacare — “to be empty” or “to be free.” The same root gives us vacuum, vacant, vacation — all words built around the idea of emptiness or absence. It entered English in the 17th century, initially used in scientific contexts to describe a literal vacuum before acquiring its cutting figurative sense of a mind or expression that contains nothing worth engaging with.

Fun Fact

The philosophical concept of horror vacui — Latin for “fear of the void” — held that nature itself abhors emptiness and will always rush to fill it. Aristotle argued that a true vacuum was physically impossible, a position that dominated scientific thinking for nearly two thousand years until Evangelista Torricelli demonstrated the existence of a vacuum in 1643 using a mercury barometer. The irony is that horror vacui turned out to describe human psychology far more accurately than it described physics — people genuinely do rush to fill empty space, empty silence, and empty conversation with whatever is available, which is precisely how vacuous content comes to occupy so much of the world.
