A hook-shaped device or curve designed to catch or grip with the fingers, often used in climbing or specialized equipment.
From English 'finger' (Old English 'fingur') combined with 'hook' (Old English 'hoc'), meaning a bent or curved catching device. The compound emerged in technical contexts during the 19th century.
