What does musty mean?
Musty is an adjective describing something that smells stale, damp, or unpleasantly old, as in a musty cellar or a musty wardrobe. It can also describe ideas, fashions, institutions, or other things that seem dated, inflexible, or out of touch with current taste. The word often carries a slightly literary or evaluative tone: describing something as musty suggests not merely that it is old, but that its age has produced an unattractive or uninviting impression. In ordinary use, musty most often refers to a physical smell, especially in enclosed or poorly ventilated spaces. Its figurative use can be stronger and more openly critical, particularly when describing cultural or intellectual trends. Although related in spelling and sound to misty, musty is not a synonym for foggy or hazy; its characteristic associations are staleness, mustiness, and age.
