Donna

I'm of Italian descent with a decent knowledge of the language. In Italian, the word 'Donna' (lowercase) predominantly means woman. With a first or last name, it can be used as a form of address. It is also used in reference to a notable woman, and in chess, another reference for the queen. I've always liked the name Donna, and its meaning makes it one of my favourites. It isn't used in Italy, but in other countries, people of Italian descent have sometimes been known to use it for their daughter, or make it part of a double name, such as Donna Jo, Donna Lee, etcetera.

Another name it can stem from is Donatella.

From Indo-European *dem- "house". (from The American Heritage Dictionary of Indo-European Roots)

Derived from Latin "domina", meaning "lady" or "woman of the house". Historically, it did mean "lady", but, as language changes, its meaning (since at least Mozart's time) is now predominantly "woman", from what I have seen.
