Exhort comes from Old French exhorter, from Latin exhortari ('to encourage strongly'), from ex- ('thoroughly') + hortari ('to urge, encourage'). Morphologically, the form is compositional: ex- marks part of the visible structure, while the remaining element supplies the lexical base. In present use, it is used as a verb meaning "to urge or encourage someone strongly to do something", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as exhortation, exhorter, exhortative, and exhortatory and related forms such as hortatory, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin exhortari and Latin hortari, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by urge, encourage, admonish, and enjoin on one side and contrasts such as dissuade, discourage, and deter on the other, locating the modern specialization without adding a new origin story.
