The term 'RECEIVE INTEREST' can be solved by the four-letter word 'EARN'. This term is used to describe the process of making money through investments, such as stocks, bonds, and other financial instruments. When an investor puts their money into these investments, they are said to be earning interest, which is a percentage of the original investment that is paid out over time. This interest can be received in the form of dividends, capital gains, or other forms of income.
