Etymology

Origin of tumultuous

First recorded in 1540–50; from Latin tumultuōsus, from tumultu(s) tumult + -ōsus -ous

Explanation

The adjective tumultuous means disruptive, troubled, or disorderly — like the tumultuous state of an unruly classroom after the teacher has stepped out for a few minutes. You might hear the adjective tumultuous in news stories about riots because it's one of the best words to describe a group of people in turmoil or disorder, but it can mean anything in a state of unrest. For example, you might steer your boat into a safe harbor before a heavy storm, so the tumultuous waves won't sweep you onto the rocks.
