Etymology

Origin of war1

First recorded before 1150; Middle English noun wer(re), war(re), late Old English werre, wyrre, from Old North French wer(r)e, waire, from Old Frankish werra (unrecorded), from Germanic; cognate with Old High German werra, Middle Low German, Middle Dutch werre “strife, discord”; verb derivative of the noun; akin to war 2, worse

Origin of war2

First recorded in 1300–50; Middle English wer(re), war(re), from Old Norse verri worse

Explanation

War is armed combat between two or more countries or between different groups of people within the same country. As the soul singer Edwin Starr asked, "War! Huh! What is it good for?" Absolutely nothing. The term "civil war" means not that the war is courteous and polite, but that it is between citizens of the same nation or community, as in the American Civil War. Often war refers to nonmilitary combat or tension, such as between angry neighbors, or rival sports teams, or between different social classes — as in "class war," or government policies such as the "war on drugs."
