The word "wreathen" is derived from the Middle English word "wrethen". It comes from the Old English word "wrǣþan", which means "to twist" or "to turn". The root of "wrǣþan" is also related to the Old Norse word "reiza", which means "to twist" or "to turn". Over time, "wrǣþan" evolved into "wrethen", and eventually "wreathen", indicating something that is twisted or turned into the shape of a wreath. The term is commonly used to describe a circular arrangement of flowers, leaves, or other materials.
