Etymology

Origin of grass

before 900; Middle English gras, Old English græs; cognate with Dutch, German, Old Norse, Gothic gras; akin to grow, green

Explanation

That short green stuff all over the front lawn is grass. What could be better than lying in the grass on a summer afternoon, gazing up at puffy clouds in a blue sky? The word grass goes back to a root that means "green." You're probably familiar with the grass in back yards and city parks. There's also the grass that covers pastures, meant for cows and sheep to graze on, and the grass of grasslands, growing wild on every continent except Antarctica. If you express envy, you may hear the phrase, "The grass is always greener on the other side." In other words, somehow other people's lives always seem better.
