The antonyms for the word "rearranged" can be "disorganized", "jumbled", "haphazard", "cluttered", or "untidy". While rearranging means changing the order or positioning of something in a systematic way, its antonyms represent the opposite. A disorganized space lacks structure and order, whereas a rearranged space has order and a clear arrangement. Similarly, jumbled or haphazardly arranged things are not arranged according to any particular pattern or system. A cluttered space is filled with a lot of stuff that is neither organized nor arranged in any particular way. Finally, an untidy space can be unpleasant to look at as it lacks cleanliness and order.
