Which word relates to the act of transferring possession of goods or property?

The term that best relates to the act of transferring possession of goods or property is "sale." In a sale, ownership of an item or property is permanently transferred from the seller to the buyer in exchange for payment. This transaction signifies a complete transfer of rights and control over the asset.

In contrast, borrowing typically implies that the item will be returned to the original owner after a specified period, thus not transferring possession outright. Leasing involves a temporary arrangement that allows one party to use property owned by another, generally involving regular payments over a set term, and does not convey ownership. Donation implies giving an item away without expecting anything in return, which also involves transferring possession, but without the financial component central to a sale. Therefore, "sale" is the most accurate term specifically denoting the act of transferring ownership through a commercial transaction.
