belladonna is the name of a poisonous plant, fitting in with the Hobbit-habit of naming girls after flowers. The word is understood as an Italian name, a rarity among Hobbits, and translates as "beautiful lady" although it derives from Latin bladone "nightshade". The name participates in a circular wordplay with the names of her sisters, Mirabella and Donnamira, also Italian names.
