IPA: /ˈkrɛdɪtə/
KK: /ˈkrɛdɪtər/
A person or organization that lends money or extends credit to another party, expecting repayment in the future.
The creditor agreed to give the borrower more time to pay back the loan.
Creditor → It is formed from "credere" (meaning to believe or trust) and "-or" (meaning one who). A creditor is one who trusts or believes that they will be repaid for the money or goods they have lent.
Think of someone who 'trusts' ('credere') that they will be 'repaid' — that's why a creditor is someone who lends money expecting to get it back.
