Pronunciation

  • IPA (Classical): [dɪsˈkɛr.noː][1]
  • IPA (Ecclesiastical): [diʃˈʃɛr.no][1]

Forms

discernō (present infinitive discernere, perfect active discrēvī, supine discrētum); third conjugation[1]

Etymology

It is from Latin dis- + cernō (“to sift, separate”).[2][3] Apuleius has a contracted perfect form, ⟨discrerit⟩.[2]

Earliest recorded meaning

Varro, in his book on farming, says the lambs are fed on milk and then separated again from their mothers.[2] Köbler dates Varro 116–27 BC.[4]

Semantic evolution

It meant to separate or set apart, as Sallust speaks of a mountain marking off territories.[5] Lewis & Short note this literal sense is frequent from the Augustan period.[6] With the mind or senses it meant to distinguish, as Cicero says someone could not tell his wife from his sister.[2] It also meant to settle a dispute, as Virgil's boundary stone placed to settle a quarrel over fields.[2] Döderlein contrasts discernere, to distinguish by judgement, with distinguere, to distinguish by marks.[7]

In medieval Latin it meant to divide and separate, and also to sift.[8] English discern is recorded in the late 14th century through Old French discerner, and English discreet comes from its participle discrētus, “discerning, careful” in medieval Latin.[3]
