Morphology

simple + interest

The components 'simple' (not complex/basic) and 'interest' (payment for borrowing) give a B1 learner a clear hint that this refers to a basic form of interest rather than a more complex one. However, the technical restriction that interest is calculated only on the original principal (not on previously earned interest) is a specialized nuance not fully predictable from the words alone, so it is only partially transparent.

Etymology

Simple interest comes from an old money idea: simple meant 'single' or 'plain', so you only pay interest on the original amount, not on interest that has already built up. That's why simple interest means interest charged only on the 'starting amount'.
