The term 'more unassembled' implies that there is still some assembly needed, but what are its antonyms? To start, 'fully assembled' or 'pre-assembled' provide the opposite meaning, suggesting that the item is entirely built and ready for use. 'Partially assembled' may suggest that some assembly has been completed but isn't fully finished yet. Conversely, antonyms such as 'completed' or 'finished' indicate that no more assembly is needed, and the item is ready for use. 'Built' and 'constructed' suggest that the assembly process has been completed, implying that the item can now be used. Ultimately, various antonyms can be used to provide a different meaning from the initial 'more unassembled'.
