fas-TID-ee-us
(adjective) Very attentive to detail; hard to please.
He was fastidious about cleanliness and reorganized the desk every day.
Fun Fact
Fastidious once had a negative connotation, implying someone overly fussy or snobbish. Today, it’s often admired in chefs, designers, and editors who demand precision. It’s also a favorite word for describing perfectionists—both lovingly and critically.
aw-STEER
(adjective) Severe or strict in manner or appearance; having no comforts or luxuries; pleasingly simple and unadorned.
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.
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.
