* "Aneta" could be a misspelling of "Anet", which is a masculine given name, or "Anita", which is a feminine given name.
* "Buena" means "good" in Spanish.
Therefore, depending on the intended spelling, the phrase could mean:
* "Anet is good" (if "Aneta" is a misspelling of "Anet").
* "Anita is good" (if "Aneta" is a misspelling of "Anita").
However, without further context, it's difficult to provide a definitive translation.
