Secular jew here with a really stupid question about the tanach
What exactly constitutes the tanach? I think I've heard it's an acronym, so would the Torah be the t? what's the rest of the acronym? Which writings does it include? I'm pretty sure the talmud isn't part of it, what else isn't? Apologies if this is too basic of a question for you!
Hello! Thank you for the question!
The Torah indeed is the first part of the Tanach. Tanach is an acronym for the Hebrew words Torah, Nevi'im and Ketuvim. Roughly translated, those titles mean "Instructions", "Prophets" and "Writings", respectively. The Tanach, then, consists of 24 books divided into those three categories.
The Torah is the easiest one to define: it's the Pentateuch, the Five Books of Moses, however else you choose to call them, and they are generally known to be set apart. The books in it are Bereshit (Genesis), Shemot (Exodus), Vayikra (Leviticus), B'midbar (Numbers) and Devarim (Deuteronomy). Those are the books traditionally given to Moshe directly by G-d, and mostly focus on the formation of the Israelite people and its time under his leadership. It also includes all the commandments, basically.
Nevi'im are supposedly the books written by prophets, and half the books there are specifically books of prophecy (which is more messages from G-d than necessarily predicting the future). However, the first four books - Joshua, Judges, Samuel and Kings - are more historical in nature, chronicling the events from Moshe's death to the destruction of the 1st Temple. The last four books - Isaiah, Jeremaiah, Ezkiel and the Twelve prophets - are primarily books of prophecies and visions, with some stories sprinked in between. Most of them are concurrent with events in the book of Kings - except for the last three of the Twelve Prophets, who have lived around the building of the 2nd Temple. The Twelve Prophets are (by this order): Hosea, Joel, Amos, Obadiah, Jonah, Michah, Naḥum, Ḥabakuk, Zephaniah, Ḥaggai, Zacharias and Malachi. Names are written more or less in their traditional English spelling.
Then we get to the Ketuvim, Written texts, which are... a little more vague. It's hard to say if there's a uniting theme. A couple are books of parables and songs are there, yet others are more chronicles of events, either ones that occured after the time of the book of Kings, before it or concurrently with it. A common assumption is that the difference between those and the Nevi'im is the level of prophecy in writing them - where the Nevi'im were written under direct prophecies, while the Ketuvim were only written in Ruach HaKodesh (roughly translated as "the holy spirit", but I don't want to cause any confusion with Christianity). Either way, the books in the Ketuvim are, in order: Tehilim (Psalms), Mishley (Proverbs), 'Iyov (Job), Shir HaShirim (the Song o Songs/the Songs of Solomon), Rut (or Ruth), Eichah (Lamentations), Kohellet (Ecclesiastes), Ester (or Esther), Daniel, Ezra (and Neḥemiah) and Divrey HaYamim (Chronicles).
If you count, you'll find there are 5 books in the Torah, 8 in the Nevi'im and 11 in the Ketuvim - 24 in total. Ther Twelve Prophets, known as Trei Asar (which just means twelve), are considered one book, The division of Samuel, Kings, Ezra and Chronicles into two books each is relatively late and only makes sense in Ezra due to the obvious PoV shift. Which kind of reminds me, maybe a brief explanation is required as to what each of those last 11 books is.
Tehilim is a book of prayers and religious poems, traditionally written by King David (though they were probably collected long after his time). Mishley is the proverbs of king Shelomo (Solomon), some of which were definitely written long after his time (as in, it's directly stated inside the book). 'Iyov is possibly a parable, possibly a real story which serves as a background to a conversation on the problem of evil that doesn't seem to be solved within the book. The five books from Shir HaShirim to Esther are considered the Five Scrolls, but actually share very little in common: Shir HaShirim is a love song that sometimes become rather erotic, written by King Solomon. Ruth is an origin story to King David's family that occurs during the Judges period, and is about his Great-Grandmother and her conversion to Judaism (she was from Moab, which was a neighboring nation). Eichah is a book lamenting the destruction of the 1st Temple and of the Kingdom of Judea, traditionally written by Jeremiah. Kohellet is a philosophical book pondering the meaning of life - it either finds none or finds solace in faith, depending who you ask - also said to have been written by King Solomon. Esther is famously about the first organised Pogrom in recorded history - one against the Jews of the Persian empire, occuring during the Babylonian exile in Persia. Daniel is about the vision of a Jewish slave in the court of Nebuchadnezzar, who somehow succeeds to stay in a position of power after multiple switches in the government. The story of Daniel isn't half as interesting as his weird visions, though. Ezra is about the rebuilding of the Temple and Jerusalem after the return from exile, more or less - Ezra and Neḥemiah are the major leaders of this time period. This is pretty much a chronicling book - as is the last one, appropriately called Chronicles (Divrey HaYamim). That one basically attempts to sum up everything that happened to the Jewish people throughout history until the building of the 2nd Temple.
I've already written a lot and am too tired to explain why those books were codified and others weren't, so I'll just leave it at that for now.
