Pronunciation

  • Classical: [ĩːˈfreː.noː][1]
  • Ecclesiastical: [iɱˈfrɛː.no][1]

Forms

īnfrēnō (present infinitive īnfrēnāre, perfect active īnfrēnāvī, supine īnfrēnātum); first conjugation[1]

Etymology

It is formed from Latin in-1 + frēnum with the verbal ending -ō.[2] frēnum (“bridle”) goes back to Proto-Italic *frēno- and Proto-Indo-European *dʰr-eh₁-no- (“holding”), an etymology de Vaan prefers to Ernout and Meillet's link with frendō (“to gnash”).[3]

Earliest recorded meaning

De Vaan dates it from Accius,[3] whose tragedies have it of curbing anger (iram infrenes).[2] The TLL notes an older fragment of Ennius, in a damaged or corrupt passage.[4]

Semantic evolution

The literal sense, “put a bridle on” a horse, is in Livy, and Virgil extended it to “harness” chariots;[2][5] Silius Italicus calls cavalry infrenati manipli.[2][5] Cicero and later authors used it figuratively for curbing a person or a passion.[2][6]

Medieval writers used it both for bridling or harnessing and for binding, curbing and subduing.[7] Old French enfrener and Spanish enfrenar continue it.[4]

  • 170–c. 90 BC – Accius uses it of curbing anger.[2][8]
