1. The act of separating grain seed from stalk, as in the verb “threshing”. Before mechanical threshers, this was done by walking or treading on the stalks by a human or animal.
2. The left-over stalk after threshing. The chaf is the technically the seed hull remnants, and the Thresh is the left-over stalk.
Threshing was done in the late fall, after harvest and just before winter. The leftover thresh was then placed over the dirt floor inside the home to act as an isulator and to absorb normal dat-to-day detrius. A wooden span was placed at the bottom of the door to keep the weather out and the thresh in, and was thus termed a thresh-hold. Over time this became a single word, threshhold. I don’t know when the second “h” was removed. Personally, I think it should be put back, but I’m kinda weird that way.]]>
