Origin & History of “grass”
Reflecting its status as the commonest and most obvious of plants (and, for agricultural communities, the most important), grass etymologically simply means ‘that which grows’. It comes from *grō-, *gra-, the prehistoric Germanic base which also produced grow (and green). this gave the noun *grasam, from which German and Dutch get gras, Swedish gräs, and English grass.
