creditor

n. lender, loaner, moneylender

A creditor is a party (e.g. person, organization, company, or government) that has a claim to the services of a second party. The first party, in general, has provided some property or service to the second party under the assumption (usually enforced by contract) that the second party will return an equivalent property or service. The second party is frequently called a debtor or borrower.
