The practice or habit of speaking or pronouncing words incorrectly or badly.
From Greek kakos (bad) and epos (word, speech), with the noun-forming suffix -y. It describes the condition or practice of poor speech as a whole rather than the person doing it.
English collected dozens of these 'caco-' words in the 1800s from Greek roots—linguists were obsessed with cataloging every possible way humans could go wrong with language!
