ETYMOLOGY
from participial stem of Latin tumultuari (to make a bustle or disturbance) + -ate
EXAMPLE
“… Secondly, beeing sued, and Iudgement passed against you, Acquiesce in the Iudgement, and doe not tumultuate against it; and take example from mee, whom you haue heard here protest, that when euer any Decree shall be giuen against me in my priuate right, betweene me and a Subiect, I will as humbly acquiesce as the meanest man in the Land. Imitate me in this, for in euery Plea there are two parties, and Iudgement can be but for one, and against the other; so one must alwayes be displeased. …”
From: James I of England
Speach Starre-chamber, 1616
