Exacerbate → It is formed from "ex-" (meaning out of or from) and "acerbatus" (meaning harsh or bitter). The word describes the act of making a situation more severe or intense, as if bringing out the harshness.
Think of 'bringing out' ('ex-') the 'harshness' ('acerbatus') in a situation — that's why exacerbate means to make something worse.
