History & Origin
Didi is a reduplicative pet name, made by doubling a soft first syllable, long used for Diana, Deirdre, Delia and others. As a legal first name it belongs to the mid-century taste for friendly nicknames given outright, its meaning borrowed from the parent name behind it.
It was never common in the United States as a given name, reaching only about twenty girls a year around 1971. A girl named Didi then is in her fifties now.
