🔡 Root

Latin fastidiosus = disdainful, squeamish; fastus = arrogance + taedium = disgust

📜 Etymology

From Latin fastidiosus 'disdainful, squeamish, exacting', from fastidium 'loathing, aversion, excessive nicety' (thought to be a blend of fastus 'arrogance, contempt' and taedium 'disgust'). Entered English in the mid-15th century.

Link "fast-tidy-ous" - someone so fast to tidy up that every speck must be perfect; a fastidious person is fixated on tidiness and detail.

🎯 How This Word Works in UPSC Writing

Very attentive to accuracy and detail, sometimes excessively so. In GS4 it cuts both ways, which is what makes it useful: fastidious record-keeping is a virtue in public office, while fastidiousness that delays decisions becomes an obstacle to service. An answer that notes where the line falls is doing the calibration the paper rewards.

⚖️ Don’t Confuse It With

Fastidious is meticulous about detail, possibly to a fault. Meticulous is careful and thorough without the negative edge. Pedantic is concerned with trivial correctness at the expense of substance. Punctilious attends closely to correct form and procedure.
