Credit is a fundamental concept in finance, representing the trust that allows one party to provide money, goods, or services to another with the expectation of repayment in the future. It can take various forms, including loans, credit cards, and lines of credit, and is often accompanied by interest charges. Creditworthiness is assessed through factors like credit scores and financial history, influencing borrowing terms and access to capital. It plays a critical role in economic growth and consumer spending.
