For example, "piece by piece" or "bit by bit" would mean breaking down something into smaller parts. "Selective" or "particular" would indicate being picky and choosing only parts of something. "Incomplete" or "partial" would indicate that something is lacking certain elements. Lastly, "piecemeal" or "disorganized" would describe something that is not complete or unified, but rather scattered or chaotic. These antonyms show how small changes in language can have a major impact on meaning.
