Etymology

It is inherited from Middle English fervent,[2][3] borrowed from Old French fervent,[4][5][6][7] and directly borrowed from Latin fervēns (“boiling, hot, glowing”),[2][3][8] the present participle of ferveō (“to boil, glow”).[4][7][5][9] Dictionary.com also notes Anglo-French as a possible step,[8] and the Anglo-Norman adjective is recorded from 1212 with the sense "ardent, passionate".[10] Etymonline, the American Heritage Dictionary and Ayto derive the Latin verb from Proto-Indo-European *bhreu- (“to boil, bubble, effervesce, burn”),[5][9][11] and Klein from Proto-Indo-European *bheru-, an enlarged form of a base meaning "to boil, seethe".[12] The same Latin verb gave effervescent and comfrey, and its derivative fermentum gave ferment;[11] Ayto connects brew, broth and fry with the same root.[11]

Earliest recorded meaning

Ardent, earnest: 1340, in the Ayenbite of Inwyt,[4][13] matching Etymonline's date of the mid 14th century.[5] The OED, not fully revised for this entry, begins with Trevisa's translation of Bartholomaeus Anglicus (before 1398), where it describes drugs as "hot" in the medieval sense.[7]

Semantic evolution

In Latin the literal sense of boiling or glowing came first, with figurative uses such as "violent, impetuous, furious".[5] In English the order of the records is reversed: Barnhart finds "ardent" in 1340 and points out that the literal sense is not recorded until shortly before 1398.[4] The Middle English Dictionary has Trevisa's "Canicula is a ful feruent sterre" for burning heat, and the same text's turbulent sea.[2] Chaucer has the word once, for "hot".[14] Sources differ on the date of "impassioned": Etymonline has it by about 1400,[5] and the OED's first record for people and their passions is from before 1500.[7] The OED adds that from the 17th century that sense was used almost only of love, hatred and zeal.[7] It was also used of intense cold, from 1448 to 1600, and of fierce conflict, from 1465, now rare.[7] Johnson (1755) separates "hot; boiling", "hot in temper; vehement" and "ardent in piety".[15] Collins now marks the sense of heat as archaic or poetic,[16] and a verb meaning "to utter fervently" is recorded only from before 1627.[7]
