frenetic

Etymology

It is inherited from Middle English frenetik, also frentik and frantik,^[2][3][1] borrowed from Old French frenetike^[4][5][1] and directly borrowed from Latin phrenēticus (“delirious”).^[3][2] The Latin word is taken from late Ancient Greek φρενητικός (phrenētikós, “delirious”),^[4][6][1] an alteration of φρενιτικός (phrenitikós, “affected with delirium”),^[4][5][3] from φρενῖτις (phrenîtis, “delirium, inflammation of the brain”),^[4][5][3][7] from φρήν (phrḗn, “mind, heart; originally the diaphragm”).^[4][5][3][8] Barnhart traces the Greek word to Proto-Indo-European *gʷʰren- (“diaphragm, as the seat of the intelligence”) and compares Old Norse grunr (“suspicion”),^[3][7][9] while Klein calls it of uncertain origin.^[8] The word was formerly stressed on the first syllable, and the OED derives frantic from that pronunciation;^[4][6] Ayto says that the change of frentik to frantic has never been explained satisfactorily.^[10] The Anglo-Norman word is recorded from the mid-12th century, for mad, frenzied or delirious and for a madman.^[11]

Earliest recorded meaning

Crazed, delirious: before 1376, as frentik, in Piers Plowman,^[3] and as frenetik about 1385, in Chaucer's Troilus and Criseyde.^[3] The OED's first record is before 1398, in Trevisa's translation of Bartholomaeus Anglicus,^[4] and Etymonline dates the word to the late 14th century.^[5]

Semantic evolution

At first the word was close to a medical term: a person temporarily out of their mind, in line with the Greek word for inflammation of the brain,^[5][2] and it described such a disease too, in use from 1609 to 1754.^[4] From the 1520s, in Skelton, it was applied to actions and qualities, meaning frenzied or wild.^[4] From about 1550 it was applied to people wildly excited or, in religion, fanatical.^[4][6] The sense "insane" had died out by 1778.^[4] The English forms split: Ayto observes that frentik became frantic, while the three-syllable French form, partly remodelled on Latin, gave phrenetic,^[10] and Etymonline notes that the classical ph- was sometimes restored from the mid-16th century.^[5] Skelton also used the word as a noun for an insane person, in 1528, now rare or obsolete.^[4][6]
