Etymology
Origin of green
First recorded before 900; Middle English, Old English grēne; cognate with German grün; akin to grow
Explanation
Green is a color on the spectrum between blue and yellow, or made by mixing those colors. You might love the brilliant color of the green grass in the spring time. Green is a color you tend to see everywhere in nature, especially in the summer. Grass, trees, and plants are varying shades of green, and so is the lettuce that's used to make "a green salad." Green also means "unripe" as in a tomato, or "inexperienced," as in someone who's new at a job. In the 16th century, Shakespeare coined the phrase "the green-ey'd monster," and since then green has symbolized jealousy or envy.
