Pronunciation

  • IPA (Classical): [ˈɫeː.nɪs][1]
  • IPA (Ecclesiastical): [ˈlɛː.nis][1]

Forms

lēnis (neuter lēne, comparative lēnior, superlative lēnissimus, adverb lēne or lēniter); third-declension two-termination adjective[1]

Etymology

It is inherited from Proto-Italic *lēni-, inherited from Proto-Indo-European *leh₁-n(o/i)- (“lazy, slow”).[2] Cognate with Lithuanian lė́nas (“slow, calm”) and Latvian lēns (“slow”), whose meaning is close enough to “soft, calm”.[2][1][3] The i-stem probably replaced an older o-stem, as in hilaris.[2] lentus is similar in sound and meaning but of a different origin.[1]

Earliest recorded meaning

Köbler and the OLD give Ennius first, who describes a river flowing with a gentle current and a quiet sleep.[4][3] De Vaan gives Plautus.[2] Köbler dates Ennius 204–169 BC.[4]

Semantic evolution

It meant slowly moving, gentle or placid, as of rivers, winds and sleep, and then mild or weak, as of fevers, slopes, drugs and fires.[3] It was used of mild tastes and wine, of soft sounds, and of people and actions that were gentle, lenient or tolerable.[3]

Döderlein contrasts lēnis, gentle as opposed to vehemēns, with mītis, mild as opposed to acerbus, and placidus, calm as opposed to turbidus.[5] Its derivatives lēniō “to soothe” and lēnitās “gentleness” gave English lenient and lenity, and English took over lenis as a term of phonetics.[1][6]

Timeline

  • 81–43 BC – Cicero uses it of a softer sound.[3][4]
