Nincompoop (noun)
nin-kom-poop
a fool
Nincompoop has a history as unusual as its meaning. One hypothesis includes connections to the Latin phrase non compos (mentis), meaning “not of sound (mind). Alternatively, nincompoop could simply be an elaboration based on ninny, which may come from innocent. Nincompoop was first recorded in English in the 1670s.
