Other forms: animadversions
Animadversion is a harsh, critical comment — or even a public censure. You don't hear it very often, but in Puritan times, dressing in bright colors and swearing would bring many animadversions down upon you.
Animadversion comes from the verb animadvert. In Middle English, animadvert meant simply to pay attention — to "turn your mind to" something, from the Latin animus ("mind") + ad- ("to") + vertere ("turn"). Anyone with parents can understand how a word that means "pay attention" can turn into a word that means "criticize."
