The artist gleaned the name from the famous Queen song Radio Gaga, but the word gaga entered the English lexicon in the early 1900s as a term for "crazy" or "silly."

　　Lady Gaga的名字源于皇后乐队的著名歌曲《Radio Gaga》。“Gaga”一词是在1900年代进入英语，意为“疯狂的”“愚蠢的”。

　　Though its origin is unknown, it may come from the French imitative gaga meaning "senile" or "foolish."

　　虽然它的词源仍然未知，但它有可能是来自法语的gaga，意思为“年老糊涂的”“愚蠢的”。

　　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.

　　如今这个词多用来形容极度迷恋某事，“going gaga”即对某事很痴迷。

　　Example：

　　I can't understand how anyone could be so gaga over golf.

　　我搞不懂为什么那么多人痴迷高尔夫。
