The word TaNaCH is actually an acronym for the parts of the Hebrew Bible: "T" is for Torah, "N" is for Nevi'im, and "CH" is for Ketuvim. The Torah is the first part of the TaNaCH.

Although most of the individual books of the TaNaCH were written well before the third century BCE, it wasn't until 90 CE in the city of Yavneh that they were all brought together.
