Perfidious

per-FID-ee-uhs

Definition

(adjective) Deceitful and untrustworthy; deliberately disloyal.

Example

His perfidious actions during the negotiation shocked even his rivals.

Word Origin

Late Middle English: from Old French perfidieux, from Latin perfidiosus, from perfidia ‘treachery’, based on per- ‘through’ + fides ‘faith’.

Fun Fact

Perfidious isn’t your average insult. It suggests a deep and knowing betrayal, often by someone who pretended to be loyal. Historically, it was used in diplomacy and politics—perfidious Albion was a nickname used by the French to accuse Britain of double-dealing. It shows up in literature, courtroom speeches, and bitter breakups. This isn’t just someone who disappointed you—it’s someone who knew exactly what they were doing.

Austere

aw-STEER

Definition

(adjective) Severe or strict in manner or appearance; having no comforts or luxuries; pleasingly simple and unadorned.

Example

The monastery’s austere design — bare stone walls, minimal furniture, and no decoration — was intentional, meant to keep the monks focused on contemplation rather than comfort.

Word Origin

Austere comes from the Greek austēros, meaning “harsh” or “rough to the taste,” originally used to describe the bitter, drying quality of unripe fruit. The word passed into Latin as austerus and then into Old French before arriving in English in the 14th century. Its early use referred to physical sensations before expanding to describe strict, unadorned behavior and environments.

Fun Fact

The ancient Spartans were the ancient world’s most famous practitioners of austerity — so much so that the word spartan itself became a synonym for bare-bones living. But “austerity” as a modern economic and political term surged in the 20th century, particularly during the Great Depression and again after the 2008 financial crisis, when governments cut public spending to reduce debt. Critics and supporters still hotly debate whether austerity measures actually work — making this a word that started describing a bitter taste and ended up at the center of global economic policy debates.
