* Satz: This is the most common and general translation of "sentence," referring to a grammatical sentence.
* Urteil: This means "judgment" or "sentence" in the legal context, as in a court sentence.
* Satzbau: This means "sentence structure" or "syntax."
So, the best translation depends on what kind of "sentence" you mean. If you're talking about a grammatical sentence, use Satz. If you're talking about a court sentence, use Urteil.
