Forms

disertē (comparative disertius, superlative disertissimē)[1][2]

Etymology

It is from Latin disertus (“eloquent; clear”) + -ē,[1][3] the participle of disserō (“to set out in words”) used as an adjective.[4] De Vaan places these words under serō2 (“to join, link”), which he traces to Proto-Italic *sere/o- and Proto-Indo-European *ser-e/o- (“to thread, tie together”).[5] Cognate with Oscan aserum (“to lay onto”) and Ancient Greek εἴρω (eírō, “to knit together”).[5]

Earliest recorded meaning

Köbler records it first in Plautus,[3] who has satin hoc plane, satin diserte … videor tibi locutus esse?, “do I seem to you to have said this plainly enough, clearly enough?”.[1][2]

Semantic evolution

In Plautus and later in Livy it means clearly and expressly, in plain words: Livy writes of something set down in a decree disertissimē plānissimēque, “most expressly and plainly”.[1][6] From disertus “eloquent” it also means skilfully and eloquently: Cicero imagines a painter who has written or spoken eloquently about painting,[1][2] and Nepos also has this sense.[6] Tacitus uses the phrase disertē saltāre, opposed to tenere dīcere.[6]

Timeline

  • c. 250–184 BC – Plautus uses it of speaking plainly.[1][3]
  • 81–43 BC – Cicero uses it of eloquent writing or speech.[1][3]
  • 59 BC–17 AD – Livy uses the superlative of an express decree.[6][3]
