Prosecute vs. Persecute

Take care to distinguish between prosecuted and persecuted, although we sincerely hope that neither word applies to you. Persecute typically has a small range of meanings, such as “to harass or punish in a manner designed to injure, grieve, or afflict.” Although the word is occasionally found in dialectal use to mean “prosecute,” many usage guides consider this to be an error. Prosecute is generally found today in a legal context (“to bring legal action against for redress or punishment of a crime or violation of law”), although the word may also be used to mean “to follow to the end” or “to engage in.” If someone is prosecuted they are being tried in a court of law; if they are persecuted they are being targeted and harassed.
