insurgent: [18] An insurgent is etymologically someone who ‘rises up’. The word comes from the Latin verb insurgere, which was formed from in- in the sense ‘against’ and surgere ‘rise’ (source of English surge and source). An insurgent is hence fairly straightforwardly a rebel, someone taking part in an uprising, a belligerent who is not part of an officially recognized fighting force.

Choice of vocabulary in this area tends to be controversial, however, and the use of insurgent to denote Iraqi irredentists after the Coalition invasion of 2003 was widely criticized – partly, perhaps, from the misconception that they were being characterized as ‘surging in’ from outside the country. The longer established insurrection [15], from the same ultimate source, is much less liable to such misunderstanding.
