Etymology

Origin of insurgent

1755–65; < Latin insurgent- (stem of insurgēns ) present participle of insurgere to get up, ascend, rebel. See in- ², surge, -ent

Explanation

An insurgent is a rebel or a revolutionary, someone who takes up arms against the authorities. Insurgent is from the Latin word “insurgentem,” literally meaning “to rise against,” so think of an insurgent as a fighter who rises against the people in power. Often insurgents are considered terrorists because they use violence to intimidate people.
