Word Origin & History
cucumber
c.1384, from O.Fr. cocombre, from L. cucumis (acc. cucumerem), perhaps from a pre-Italic Mediterranean language. Replaced O.E. eorþæppla (pl.), lit. "earth-apples." Cowcumber was common form 17c.-18c., and that pronunciation lingered into 19c. Planted as a garden vegetable by 1609 by Jamestown colonists. Phrase cool as a cucumber (c.1732) embodies ancient folk knowledge confirmed by science in 1970: inside of a field cucumber on a warm day is 20 degrees cooler than the air temperature.
