Turfgrass is formed from "turf" (from Old English *turf*, meaning a piece of grass-covered soil) and "grass" (from Old English *græs*, meaning grass or herb). The word refers to a type of grass that is cultivated for lawns and sports fields, emphasizing the grass-covered soil.
Think of 'turf' as a piece of grass-covered soil and 'grass' as the plant itself — together, they describe a specific type of grass that grows on soil.
