A stone used to crush grain.

[Odessa Dawn]

My ancestors used to crush grain into flour using a stone. But it is no longer working. It can be found in national heritage. I try my best to find the appropriate name for that kind of primitive machine. Is it a traditional hand mill?

I ask you such a question because I came across a hand mill while I was reading Matthew 24:41 Two women will be grinding with a hand mill; one will be taken and the other left.

It is the one in the middle of the picture. It resembles pillow.

But why not just call it a hand mill?

This is an image of flat "quern stones". These are medieval French examples.

The equivalent word in American English is "metate" (may-tah-tay). This is an entirely borrowed word from an ancient native population in Mexico or Central-South America. I do not know more exactly its origin, but many of them have been found and collected as artifacts in the southwestern United States. The word is in current use as their name can be found in our current dictionaries.

Thank you, Raymott, and I will call it a hand mill and listen to your intellect suggestion. However, when I checked Google, different kinds emerged.
Besides, it didn’t mention that stone in the picture I brought. As a result, I just wanted to consult you, native speakers, before inventing term has nothing to do with English language.
