First, to call a terrorist a “jihadist” or “jihadi” effectively puts any campaign against terrorism into the framework of an existential battle between the West and Islam. This feeds into the worldview propagated by Al Qaeda. It also serves to isolate the tens of millions of Muslims who condemn the violence that has been perpetrated in the name of Islam.

Second, these words locate the ideological battle exactly where the extremists want it to be. The terms of discussion are no longer about the murder of innocents in terrorist acts; they are about theology.

Third, when American leaders use this language it sends a confusing message to the Muslim world, showing ignorance on basic issues and possibly even raising doubts about American motives. Why, after all, would we call our enemy a “holy warrior”?

If we want to say what we mean, what terms better describe Qaeda members and other violent extremists? “Muharib” or the more colloquial “hirabi” or “hirabist” would be good places to start. “Hirabah,” the base word, is a term for barbarism or piracy. Unlike “jihad,” which grants honor, “hirabah” brings condemnation; it involves unlawful violence and disorder.
