Few of us have avoided getting one of Lady Gaga's catchy pop songs stuck in our heads, but the origin of her name is harder to find. The artist gleaned the name from a Queen song, but the word
entered the English lexicon in the early 1900s as a term for "crazy" or "silly." Though its origin is unknown, it may come from the French imitative gaga meaning "senile" or "foolish." Today the word is most commonly used in the sense of deep infatuation, where going gaga for something is the same thing at "mooning over" it.
