KK: /ˈbraʊnˌfɪld/
A type of land that was used for industrial or commercial purposes but is now abandoned or not fully used, often with pollution issues, and can be redeveloped.
The city plans to transform the brownfield into a park and housing area.
Brownfield is formed from "brown" (from Old English "brūn", meaning dark or dusky) and "field" (from Old English "feld", meaning open land or field). The term refers to previously developed land that is not currently in use, often associated with environmental contamination.
Think of 'brown' as a color often associated with land that has been used before, and 'field' as open land. Together, they help you remember that a brownfield is land that has been previously developed.
