What does untidiest mean?
Untidiest is the superlative form of the adjective untidy, meaning more untidy than anything else in a stated group or comparison. It describes the place, object, arrangement, or set of actions that has the greatest disorder, clutter, or lack of neatness. For example, a room can be untidy, but a room described as untidiest is the most disordered room in the comparison. The word is standard in both British and American English, though messiest may sound more idiomatic in casual conversation, while most untidy can be more neutral. Untidiest is most often used predicatively, as in “This is the untidiest desk I have ever seen,” but it can also modify a noun directly, as in “the untidiest corner of the house.” Its force comes from the comparison implied by the ending -est: it identifies a maximum rather than merely indicating disorder. It is ordinary, expressive vocabulary rather than specialist or highly formal terminology.
