Protest: A statement or action expressing disapproval of or objection to something.

‘Protest’ came into the English language in about 1400 CE, it came from French and derives from their word ‘preotester’ which was in turn from the Latin ‘protestari’, both meaning ‘to declare publicly’. ‘Protestari’ was a combination of two Latin words; ‘pro’ meaning ‘forward’ and ‘testari’ which meant ‘testify’.
