Word Origin and History for ammunitions



1620s, from French soldiers' faulty separation of Middle French la munition into l'ammunition; from Latin munitionem (nominative munitio) "a fortifying" (see munition), and at first meaning all military supplies in general. The mistake in the word perhaps was by influence of French a(d)monition "warning." The error was corrected in French (Modern French munition), but retained in English.
