What does untidier mean?
Untidier is the comparative form of untidy and means more untidy, messy, or disorderly. It is commonly used to compare two people, places, situations, or states: one may be untidier than another, or a space may become progressively untidier as materials accumulate. The word can also serve as a comparative adverb, describing how someone performs an action: "He arranged the documents untidier than before." Its related adjectives, untidy and untidiest, form a standard three-part comparison, while untidily and untidiness provide adverbial and noun forms within the same word family. Untidier is useful when degree matters rather than simply stating that something is disorganized. It is understood throughout British and American English and carries a largely neutral connotation, though it often implies clutter, poor organization, or lack of care.
