How do you spell Buda?

Excuse me, could you possibly clarify the spelling of the term "Buda"? I'm not entirely certain how it's meant to be written, and I'd like to ensure that I'm understanding it correctly. Could you perhaps spell it out for me, letter by letter, so that I can properly record or use it in the context I'm working with? I'd greatly appreciate any assistance you can provide in clarifying this for me.
