exhort [ɪɡˈzɔrt]
verb

To exhort someone is to try to strongly urge them to do something.

Arriving in the 15th century from the Anglo-French word exorter, exhort traces back further to the Latin verb hortari, meaning “to incite to action, urge on, or encourage.” Latin users added the prefix ex- to hortari to intensify it; in essence, exhortari is a succinct way of saying “to really, really urge.”
