Word Origin and History for earnestly



from Old English eornoste (adj.) "zealous," or from Old English noun eornost "seriousness, serious intent" (surviving only in the phrase in earnest), from Proto-Germanic *ern "vigor, briskness" (cf. Old Saxon ernust, Old High German arnust "seriousness, firmness, struggle," German Ernst "seriousness;" Gothic arniba "safely, securely;" Old Norse ern "able, vigorous," jarna "fight, combat"). The proper name Ernest (literally "resolute") is from the same root. Related: Earnestly; earnestness.
