Origin of decimate

First recorded in 1590–1600; from Latin decimātus, past participle of decimāre “to punish every tenth man chosen by lot,” verbal derivative of decimus “tenth,” derivative of decem “ten”; see ten, -ate1

historical usage of decimate

The earliest English sense of decimate is “to select by lot and execute every tenth soldier of (a unit).” The extended senses “to destroy a great proportion of; greatly reduce or damage” have been criticized on etymological grounds, although these usages are common in standard English: Cholera decimated the urban population. Because the etymological sense of one-tenth remains to some extent, decimate is not ordinarily used with exact fractions or percentages: Drought has destroyed (not decimated ) nearly 80 percent of the cattle.
