Easily Confused

pecuniary vs financial vs monetary — financial is the broad everyday word (financial planning, financial trouble); monetary is about money supply/policy (monetary policy, monetary value); pecuniary is narrow and formal, almost always about money as a measurable gain, loss, or interest, especially in legal settings. You wouldn't say 'pecuniary policy.'
