Greenfield → It is formed from "green" (from Old English "grene", meaning the color of growing plants) and "field" (from Old English "feld", meaning an open land or area). The word "greenfield" refers to an area of land that is undeveloped or not built upon, often characterized by greenery and open space.
Think of 'green' as the color of growing plants and 'field' as an open area — together, they describe a space that is lush and undeveloped.
