Etymology tree
Forms
tumultuōsus (feminine tumultuōsa, neuter tumultuōsum, comparative tumultuōsior); first/second-declension adjective[1]
Etymology
It is from Latin tumultus (“commotion, uproar”) + -ōsus.[2][1][3] De Vaan thinks that the meaning of tumultus points to tumeō (“to swell”), although its formation is unclear; he traces that verb to Proto-Italic *tum-ē- and Proto-Indo-European *tum-eh₁- (“to be swelling”).[4] He compares Lithuanian tumė́ti (“to become thick”).[4]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus,[4][5] in whom someone asks who has called him out of doors with such a noisy din, tam tumultuoso sonitu.[6]
Semantic evolution
It means full of commotion or uproar, disturbed and noisy:[2] Cicero speaks of a seditious and turbulent life and of stormy public meetings, and Quintilian of a tumultuous delivery.[6] Of people and countries it is unruly or turbulent, as in Livy's reproach of men “turbulent in peace, sluggish in war”, and it is also used of storms and other natural forces.[2] In Livy a report can be tumultuosus, received with wild alarm, as when horsemen rush in with the news that the Volsci are coming.[2] English tumultuous (1540s) came from it through French.[3]
