The day ends and the night begins The moon reigns while the sun rests The night ends and the day begins The sun reigns while the moon rests Every end is a new beginning And every beginning has an end This eternal infinite cycle keeps the universe in continual perpetual action!
Essentially, a nincompoop is a fool, a stupid person whose incompetence or naïveté is quite apparent. It is often used to describe people of a much lower social ranking, although some may describe an unpopular or incompetent leader as an "utter nincompoop." It is conceivable that the originator of "nincompoop" was seeking to combine several unsophisticated words into one nonsensical but descriptive word.
