Morphology

compound + interest

The word 'compound' conveys the idea of combining or adding, so a learner who knows both words can often infer that 'compound interest' is a type of interest that is added or accumulated rather than a completely new meaning. However, the precise technical sense — interest calculated on both the principal and previously earned interest — is specialized and not fully predictable from the constituents for an average B1 learner without some exposure, so the transparency is partial.

Etymology

Compound interest gives a simple picture: imagine a small snowball that grows as it rolls because the bank adds the interest to your original money, so next time you earn interest on the bigger amount. That's why 'compound interest' means you earn interest on your original money and also on the interest it already earned.
