What does moldiest mean?
Moldiest is the superlative form of the adjective moldy, meaning more affected by mold or mildew than anything else in a comparison. It describes food, surfaces, rooms, clothing, or objects that have developed mold because of dampness, poor storage, or age, and it may also convey an extreme musty or spoiled quality. The word is especially common when identifying the worst-affected item in a group: one might discard the moldiest piece of bread or complain about the moldiest corner of a room. Its connotations are strongly negative, emphasizing decay, unsanitary conditions, neglect, or the passage of time. In British English, the standard spelling is usually mouldiest. The word is particularly useful when a direct, emphatic comparison is needed rather than a neutral description of something merely moldy.
adjectiveThe most affected by mold or mildew; the most covered in, spoiled by, or tainted with mold. It can also mean the most musty or decayed in quality.
