What does mouldier mean?
Mouldier is the comparative form of the adjective mouldy. It means that something has more mould, fungal growth, or associated decay than another thing. The word is most often used with food, especially bread, cheese, fruit, and other perishable foods, and it can imply that the item is spoiled or unsuitable for consumption. In British English the standard spelling is mouldier; American English commonly uses moldier. As a comparative, it is typically used with than or in expressions such as increasingly mouldier, although it may also appear after a linking verb: “the cheese is mouldier than it was yesterday.” While mouldy is much more frequent in ordinary speech, mouldier is useful when making a direct comparison or describing a worsening change. It is not generally used for a person, except figuratively when describing a place, object, or reputation as decayed or disreputable.

Where does mouldier come from?
Mouldier derives from mouldy, which combines the older word for mould with the adjective-forming suffix -y. The spelling mould is the traditional British form; American English has traditionally used mold. The word mould ultimately comes through Old French from Latin mollis, meaning “soft,” reflecting the way mould develops on soft or organic material. The related form mouldy has been in English since the Middle English period and has continued in modern usage with both British and American spelling conventions.
