Stage of in this word's full journey.
Where does the word "cheap" come from? It comes from Latin caupo, passing through West Germanic and Old English before entering English (1500s).
Cheap’s story begins in Latin: caupo meant “innkeeper, huckster.” A tavern-keeper or petty trader, the kind of Roman merchant Germanic peoples met along the frontier. By ancient, the word had taken hold in West Germanic as *kaupōn. Turned into a verb 'to trade', the source of German kaufen 'to buy'. From there it passed into Old English as cēap by medieval. A market or bargain, surviving in London's Cheapside and towns like Chipping Norton. It reached English by 1500s as cheap. Shortened from 'good cheap', a good bargain, to mean low-priced. Today, cheap means low in price; of poor quality.
