noun. stiff dry grass, bent, stiff dry grass, bent [as a type of grass]

A noun in The Etymologies of the 1930s glossed “stiff dry grass, bent” under the root ᴹ√STAR “stiff” (Ety/STAR). In theory “bent” may be an adjective, but more likely it refers to the species of stiff grass often used in lawns.
