Abjure

ab-JOOR

Definition

(verb) To solemnly renounce or reject a belief, cause, or claim; to formally swear off something

Example

After years in the extremist group, he publicly abjured its ideology and dedicated himself to counter-radicalization work.

Word Origin

Abjure comes from the Latin abjurare — from ab (“away”) + jurare (“to swear”) — literally meaning “to swear away.” In medieval legal and religious contexts, abjuring was a formal, binding act: a person could abjure a heresy before a church tribunal or abjure the realm, swearing under oath never to return to a country.

Fun Fact

Abjuring the realm was a real and dramatic legal practice in medieval England. A person who had committed a crime could claim sanctuary in a church, and if they confessed to a coroner and agreed to abjure the realm — swearing to leave England forever via a designated port — they could avoid execution. They were required to walk barefoot, carrying a wooden cross, to the nearest port and depart within a set number of days. Straying from the road meant forfeiting their protection entirely.

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.
