Pertinacious

per-tuh-NAY-shus

Definition

(adjective) Holding firmly to an opinion, purpose, or course of action; extremely persistent.

Example

Despite repeated setbacks, her pertinacious pursuit of the project impressed everyone on the team.

Word Origin

From Latin pertinax, meaning “very tenacious” or “holding fast.”

Fun Fact

Pertinacious is stronger than persistent—it suggests a stubborn, almost unshakeable grip on a goal or belief. Historically, the word was sometimes used critically, implying someone who refused to yield even when logic (or politeness) suggested they should. Today, it often carries admiration: pertinacious people are the ones who push breakthroughs, finish impossible tasks, and stay steady when others waver.

Abate

Definition

(verb) To reduce in intensity, force, or amount; to become less severe or widespread.

Example

The protests didn’t end so much as abate — the crowds thinning gradually over three weeks until one morning the square was simply empty again.

Word Origin

Abate derives from the Old French abatre, meaning “to beat down” — built from a- (“to”) and batre (“to beat”), itself from the Latin battuere, meaning “to beat” or “to strike.” The same root gives us batter, battle, and combat — all words built around striking. The sense in abate is of something being beaten back, reduced, pushed down from its peak — not eliminated but diminished to something more manageable.

Fun Fact

In English law, abatement has a precise and ancient legal meaning — the right to remove a nuisance that affects one’s property or public space. The doctrine of abatement of nuisance dates to medieval common law and gives individuals and authorities the right to reduce or eliminate conditions that cause harm, from flooding to noise to unsafe structures. The legal phrase “abate a nuisance” has been used continuously in English courts for over six centuries — making abate one of the few words whose legal and everyday meanings have remained almost perfectly aligned across that entire period.
