shopper

The word 'shopper' is a transparent English compound built from the native Germanic root 'shop' and the agentive suffix '-er'. The root 'shop' itself evolved from the Old English 'sceoppa', meaning a booth or stall for trade, a sense which broadened to mean the act of visiting such places to purchase goods. The highly productive suffix '-er', denoting "one who does something," is directly inherited from the Old English agent noun ending '-ere'. Therefore, the literal construction "one who shops" perfectly captures the modern meaning, illustrating a straightforward and logical morphological process within the English language.
