Forms

tranquillē (comparative tranquillius, superlative tranquillissimē)[1]

Etymology

It is from Latin tranquillus (“calm, quiet”) + -ē.[2][1][3] De Vaan finds the origin of tranquillus unclear: an old explanation from trāns and a root for “quiet” fits neither the meaning nor the sound changes well.[4]

Earliest recorded meaning

Köbler and Conte cite it first from Plautus, in the Cistellaria.[3][5]

Semantic evolution

It meant “in an undisturbed manner, quietly, calmly”.[2] Cicero uses it in the Tusculan Disputations and the Orator,[6][5] and Livy has it too.[5] Seneca has the comparative of the soul that will abide more clearly and calmly among divine things,[7] and Suetonius the superlative (tranquillissime senuit, “he grew old most peacefully”).[7][6]

Medieval writers used it of living or governing in peace, as Alcuin does.[8]
