The word green comes from the Middle English and Old English word grene, which, like the German word grÃ¼n, has the same root as the words grass and grow. It is from a Common Germanic *gronja-, which is also reflected in Old Norse grÃ¦nn, Old High German gruoni (but unattested in East Germanic), ultimately from a PIE root * ghre-to grow, and root-cognate with grass and to grow.
