Etymology: "Overpromised" is the past tense and past participle of "overpromise," which is built from the prefix "over-" attached to "promise." The prefix "over-" in this sense means "too much" or "excessively," as in "overeat" or "overdo," so the verb means to promise more than one can deliver. Its parts are straightforward: "promise" comes from Latin "promissum," something sent forward, and the prefix simply adds the sense of excess.

Synonyms: overcommitted, overstated, exaggerated, overextended, misrepresented
