What does mellow mean?
Mellow describes something that is pleasantly soft, gentle, and relaxed, or that has become less intense and more settled over time. A mellow person is easy-going and unhurried, while a mellow voice or sound is smooth and lacks harshness. The word can also describe flavors, colors, light, wine, and fruit that have developed a soft, harmonious quality. As a verb, mellow means to become or cause something to become milder, calmer, or more mature. It is common in both British and American English and can be affectionate or mildly informal when applied to a person's temperament. The word is especially effective for suggesting a gradual transition: emotions mellow, fruit mellows on the vine, and harsh flavors mellow as they age.

Where does mellow come from?
The English word developed from Middle English forms related to the Old English sense 'mild' or 'soft.'
