Origin and Evolution of lunacy

First Known Use: 1250 year

Language of Origin: Latin

Story behind the word: The word 'lunacy' originated from the Latin word 'lunaticus', which means 'moonstruck' or 'affected by the moon'. In ancient times, it was believed that the phases of the moon could influence a person's mental state.

Evolution of the word: Over time, the word 'lunacy' evolved to refer to a state of mental derangement or insanity, regardless of any connection to the moon. The term is now used to describe irrational or wild behavior.
