Pronunciation

  • IPA (Classical): [ˈkɛr.noː][1]
  • IPA (Ecclesiastical): [ˈt͡ʃɛr.no][1]

Forms

cernō (present infinitive cernere, perfect active crēvī, supine crētum); third conjugation[1]

Etymology

It is inherited from Proto-Italic *krin-e/o-, inherited from Proto-Indo-European *kr̥-n-i- (“to sift, separate”), a nasal present of the root that Wiktionary gives as Proto-Indo-European *krey- (“to sieve”).[2][1] Its original participle became the adjective certus, and the verb formed a new participle, crētus, after the perfect crēvī.[2][1]

Cognate with Ancient Greek κρίνω (krī́nō, “to separate, judge”),[2][3] and related to crībrum “sieve” and crīmen.[3][1]

Earliest recorded meaning

It is found from Plautus onwards.[2] Cato tells the farmer to pass dried iris root through a sieve, per cribrum cernas.[3]

Semantic evolution

Its first sense was to sift.[3] From this it came to mean to distinguish or separate, and to decide, as in Cicero's law “whatever the senate has decided”.[3] Cernere hereditatem was to formally accept an inheritance.[3]

From distinguishing came seeing clearly, as in Ennius' “I see a light in the sky”, and grasping with the mind.[3] Cicero also used it for examining something.[3] Its compounds dēcernō and discernō gave English decree and discern.[2][4] It survives as Romanian cerne, Italian cernere and Spanish cerner “to sift”.[1]
