Etymology
The adjective meaning serious is inherited from Middle English ernest,[2][3][4] inherited from Old English eornoste (“zealous, serious”),[3][4][5] from the noun eornost (“seriousness, zeal, battle”),[3][4][6][7] which survives in the phrase in earnest.[3][8] The noun is from Proto-Germanic *ernustuz,[9] cognate with Old Saxon ernust, Old Frisian ernst, Old High German ernust and German Ernst,[3][10][2][11] and is probably a suffixed form of the base of Old Norse ern (“brisk, vigorous”) and Gothic 𐌰𐍂𐌽𐌹𐌱𐌰 (arniba, “safely, surely”),[10][7][12][13] whose further origin is uncertain.[10][7] Etymonline and Barnhart trace it to Proto-Indo-European *er- (“to move, set in motion, rise”),[3][2] and Barnhart compares Ancient Greek ὄρνυμι (órnumi, “to set in motion”);[2][14] Ayto describes the Germanic base as meaning vigour or briskness.[15] The OED treats the English adjective as either formed from the noun or inherited from the same Germanic base.[10]
Earliest recorded meaning
As an adjective, of a person, serious and sincere, in Cynewulf's Christ;[10] as a noun, seriousness, in Wulfstan, and ardour in battle, in Ælfric.[10] Ayto says the Old English noun first seems to have meant intense passion, especially zeal in battle.[15]
Semantic evolution
Ayto calls the word much more "red-blooded" at first: by the end of the Old English period its meaning was already softening from intensity of feeling to seriousness, as opposed to frivolity,[15] and the battle sense died out about 1430.[10] The noun, seriousness, is now rare except in the phrase in earnest, recorded from Old English,[10][12][8] and its intensified form in good earnest (1477, Caxton).[10] The adjective was applied to words and actions from before 1456 (Lydgate),[10] and to weighty matters from 1533.[10] Johnson (1755) defined it first as ardent or zealous in any affection.[16] Ayto sees the process ending in the modern overtone of excessive seriousness.[15] The proper name Ernest comes from the same root.[3][13]

Etymology
The pledge is inherited from Middle English ernest, earlier ernes,[3][4][2][7] probably borrowed from Old French erres (“pledges, earnest money”), the plural of erre (“pledge”),[2][4][13][17][12] altered by association with words in -ness.[2][7][10][5] Merriam-Webster gives the source as Anglo-Norman arres or erres.[4] Hoad and the OED instead consider an alteration of the synonymous arles, in Middle English erles;[7][10] the OED, which calls the origin uncertain, treats the 13th-century Anglo-Norman ernes and ernest as probably taken from English.[10] The French word is from Latin arra, also arrha, short for arrabō,[2][13][18][17] from Ancient Greek ἀρραβών (arrhabṓn, “earnest money, pledge”),[13][2][18] which is generally taken to be of Semitic origin, compared with the Hebrew word for a pledge.[13][3][4][18] The final t appeared before 1400, through confusion with earnest1, as if a bargain were made "in earnest".[2][3][4]
Earliest recorded meaning
Money paid as a first instalment to secure a bargain or contract: 1221,[10] although the OED notes that this first record may be of the Anglo-Norman word.[10] Etymonline and Barnhart date the form ernes to about 1200.[3][2]
Semantic evolution
Already by about 1225, in Saint Juliana, the word was used figuratively for a pledge or foretaste of something to come,[10][3] In Middle English it was sometimes spelled erness, which suggests that it was taken as er, early, with the suffix -ness.[3] Weekley notes that the two words earnest were often punned on.[8] A verb earnest, to secure with earnest money, was used from before 1425 to 1794.[10] In 17th-century thieves' cant earnest was a share of the booty, as in tip me my earnest, "give me my share".[19][10] In English dialects the word kept the sense of money that seals a bargain, especially the shilling given to a farm servant when hired for a year.[20]
