asperse

Asperse Has Latin Roots

You may be more familiar with the idea of "casting aspersions" than with aspersing, although they mean essentially the same thing; the word aspersion can mean "a sprinkling with water" or, more commonly, "a false or misleading charge meant to harm someone's reputation." Both asperse and aspersion are descendants of the Latin verb aspergere, meaning "to sprinkle." Asperse is the older word, dating to at least 1490; aspersion is known to have first appeared in print in English in the latter half of the 1500s.
