Definition of mellow

The word "mellow" has a fascinating history! Its origin dates back to the 15th century, when it was used to describe something that had been softened or tempered, like metal or wood, through heat or fire. From this sense of transformation, the word "mellow" began to be used to describe anything that had been made gentle or smooth through experience or age. For example, a mellow fruit might be one that has ripened or a mellow person might be someone who has become more relaxed and accommodating with time. In the 19th century, the word gained a new connotation, referring to a pleasant, rich, and full-bodied flavor or tone, particularly in music. Today, the word "mellow" is often used to describe a relaxed, laid-back atmosphere or a person who is easy-going and good-natured.
