Origin

Middle English: from Old French lunatique, from late Latin lunaticus, from Latin luna 'moon' (from the belief that changes of the moon caused intermittent insanity).

loon from [late 19th century]:
This word for ‘a silly person’ comes from the North American loon (mid 17th century), a large water bird also known as a diver. It gets its name from its distinctive cry. The sense silly is from the bird's actions when escaping from danger; perhaps influenced by loony, a mid 19th-century abbreviation of lunatic (Middle English) from Latin luna ‘moon. In the past people thought that the phases of the moon could affect people.
