What does punctilious mean?
Punctilious means showing exceptional care over small details, precise rules, and correct procedure. The word is often used for people who check their work thoroughly, follow conventions exactly, or leave nothing to chance, as in describing an editor as punctilious. It can also carry a mildly critical implication, suggesting that such care has become excessive or overly fussy. Punctilious is related in meaning to meticulous, precise, scrupulous, and fastidious, but it tends to emphasize both accuracy and attention to formal details. Its distinctive force comes from the idea of treating every small requirement as significant, whether that requirement concerns spelling, etiquette, measurements, or institutional procedure.

Where does punctilious come from?
Punctilious derives from Latin punctilium, a diminutive of punctum, meaning a point or small mark, and through the adjective form punctiliosus, meaning exact or scrupulous about small points. English borrowed the word in the 17th century in the sense of expressing a small point precisely, after which it broadened to refer to careful attention to detail and exact observance of rules. Its relatives include punctual, punctuate, and point, all associated with the Latin root for a point or mark.
