Today’s word: clod.

Clod doesn’t have an exact time period of its origin, something you should probably get used to. It comes from the Old English clod-, which was a prefix that was part of words like clodhamer, which literally translates to field-goer. Clod- comes from the Proto Germanic kludda- and the Proto Indo European gleu, clay and glei, stick together. And yes, it’s the origin word for clay, as well as glue and gluten, and probably clot too.
You clods.
