Cacoepy (Noun)

Pronunciation: [kæk-'o-ê-pee or 'kæk-o-e-pee]

Definition: Incorrect pronunciation.

Usage: Occasionally, we need words we have long since abandoned or that have abandoned us. We may be facing a period in our history now when we need to retrieve "cacoepy" from our lexical attic. "Cacoepy" is not to be confused with cacology "bad choice of words." The antonym of "cacoepy" is orthoepy "the correct pronunciation of words." "Cacoepistic" is the adjective form of today's word and a person who often mispronounces words is a "cacoepist." [...]

Etymology: The first part of today's word comes from the Greek kakos "bad." The PIE root is kakka- "to defecate." Words like "poppycock" and "cacophony" have their origins in the same root. The second half, -epy, is from Greek: epos "song, word." Its PIE root is wekw-, which also turns up in "vocal," "voice," "invoke" and "vote."
