A follow up from yesterday's class:
This morning, it struck me that the Torah, in a written book format, is called a Chumash. The scroll is a Sefer Torah. Yet, the Tanakh acronym includes "Torah." So, since the Tanakh is not a scroll, I'm curious as to why it's Tanakh, instead of something like "Chnakh" ( or whatever the proper grammatical convention would dictate).
Any insight would be appreciated!
