The word implies that such a killing was especially unnecessary, brutal, and indiscriminate. An event in which soldiers kill many civilians could be called a massacre. Mass shootings are massacres.

Etymology

Origin of massacre

First recorded in 1575–85; (noun), from Middle French massacre, noun derivative of massacrer, Old French maçacrer, macecler, probably from unattested Vulgar Latin matteūcculāre, verbal derivative of unattested matteūca “mallet” ( mashie, mace ¹ ); (verb) from Middle French massacrer

Explanation

A massacre is a big bloody mess of killing, and usually for no good reason. Not that there’s ever a good reason for killing, but massacres are especially pointless and gory. It’s unclear where the word massacre came from, but possibly it was the Old French word macacre, which means “slaughterhouse.” As a noun, massacre is a brutal slaughter of humans or animals, and it can be a verb as well, like when an army massacres an entire village of innocent people. Pronounce it like MASS-uh-ker, and remember to spell it with an acre at the end, which is how much land is needed to bury the bodies after a massacre.
