"beautiful lady"
The name Belladonna is commonly a female name from the "Italian" origin that means "beautiful lady".
Belladonna is an Italian phrase made of bella (beautiful) and donna (lady, woman), literally "beautiful lady". The same word is the English common name of Atropa belladonna, the deadly nightshade, and that botanical use is where the word is most widely encountered in English. As a given name it appears in United States birth records only from 2001.
The pronunciation of Belladonna is bel-uh-DON-uh.
