Where it comes from
First attested in the beginning of the 15th century, in Middle English; inherited from Middle English dulcoraten, from dulcorat(e) (“sweetened”, used as the past participle of dulcoraten) + -en (verb-forming suffix), borrowed from Latin dulcōrātus, perfect passive participle of dulcōrō (“to sweeten”), see -ate (verb-forming suffix).
