Mellower → It is formed from "mellow" (from Old English *melwe*, meaning soft or ripe) and the comparative suffix "-er" (meaning more). The word "mellower" means more mellow or softer in quality.
Think of something becoming 'softer' or 'riper' — 'mellow' describes that quality, and '-er' indicates more of it.
