Parcelling out refers to the process of dividing something into smaller portions. Antonyms for this term can include combining, merging, or consolidating. Combining involves bringing things together into a single entity, while merging typically refers to the joining of two equal entities. Consolidating involves strengthening or uniting several parts into one whole. Other antonyms could include gathering, amassing, or accumulating, which refer to the act of collecting or accumulating in larger quantities. In contrast to parcelling out, these terms suggest a larger or more cohesive arrangement rather than a subdivision of individual parts.
