Greener → It is formed from "green" (from Old English *grēne*, meaning the color of growing grass or foliage) and "-er" (meaning one who or that which). The word "greener" refers to something that is more green in color or a person who is inexperienced or new to a particular field.
Think of the color of fresh grass ('green') and how adding '-er' indicates more of that quality. So, 'greener' means more green or someone who is new and inexperienced.
