Answer:
Principal
Explanation:
A loan can be defined as the lending of money, property, etc by one party to another party. A loan is more often than not given out by financial institutions.
The money is loaned between parties, the original amount borrowed by the receiving party is called the PRINCIPAL.
This principal begins to reduce as soon as the money starts to be paid back.
Every principal(loan) has an interest. The interest is always at a particular rate, spread over a period of time, etc.
