On 'The Simpsons', what was Maggie's first word?

Margaret Evelyn "Maggie" Simpson is a fictional character in the animated television series The Simpsons. She first appeared on television in the Tracey Ullman Show short "Good Night" on April 19, 1987. Maggie was created and designed by cartoonist Matt Groening while he was waiting in the lobby of James L. Brooks' office. She received her first name from Groening's youngest sister. After appearing on The Tracey Ullman Show for three years, the Simpson family was given their own series on the Fox Broadcasting Company which debuted December 17, 1989.

Although she had previously spoken in fantasies and dream sequences, Maggie's first word spoken in the normal continuity of the series occurred in "Lisa's First Word", when she was voiced by Elizabeth Taylor. Although it was only one word ("Daddy"), Taylor had to record the part numerous times before the producers were satisfied.
