Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. A greenhorn is someone who has no experience. who is new to a situation. But in the fifteenth century, a greenhorn was a young cow or ox whose home had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today--a person who is new in a job.
