Lend leases refer to a legal agreement where property is given to someone for a specified period of time, and the owner maintains the ownership of the property. Antonyms for lend leases would indicate some form of ownership transfer, rather than temporary possession. For example, the antonyms for lend leases could be terms like "sale," "gift," "bequeath," or "donate." These terms denote a permanent transfer of ownership where the receiver becomes the rightful owner of the property. Additionally, terms like "seize," "confiscate," or "repossess," which indicate the legal action taken by the property owner to regain control over the property, could also be antonyms for lend leases.
