Offloaded, a term commonly used in logistics, refers to the act of unloading goods from a transportation vehicle. Its antonym, loaded, refers to placing goods or cargo onto a transportation vehicle. However, other antonyms for offloaded could include kept on board, retained, or loaded back. These terms imply that the goods were not removed from the transportation vehicle and were either kept on board for further transport or retained in the vehicle for storage. Offloaded may also have a negative connotation, implying that something was removed or dumped, so synonyms like retained or kept on board may be preferred in certain contexts.
