punk-TIL-ee-us
Definition
(adjective) Showing great attention to detail or correct behavior; strictly attentive to rules and etiquette
Example
The punctilious editor caught every misplaced comma and inconsistent font size before the report went to print.
Word Origin
Punctilious derives from the Italian puntiglio and Spanish puntillo, both meaning “a fine point” — diminutives of punto, meaning “point,” from the Latin punctum. It entered English in the 17th century to describe someone obsessively attentive to the fine points of conduct, protocol, and procedure.
Fun Fact
Punctiliousness has historically been both admired and mocked depending on context. In the courts of 17th and 18th century Europe, strict adherence to etiquette was considered a mark of high breeding — entire books were written codifying the correct way to bow, address a duke, or fold a letter. But the same quality tipped into satire just as easily: novelists like Jane Austen skewered punctilious characters mercilessly, using their rigid rule-following as a lens for social comedy. Today the word carries a faint whiff of both — respect for the detail-obsessed, and gentle amusement at their expense.
