What is the original language of word cot?

The word "cot" has an interesting origin story. It is believed to have come from the Old French word "coit," meaning "a bed" or "a small bed." This word, in turn, likely stemmed from the Latin word "cubitum," meaning "elbow," which may have been used figuratively to describe the resting position of the arm on a bed.

Over time, the word "coit" evolved into "cot" in English, and the meaning shifted to specifically denote a small, simple bed, often one used for sleeping in a temporary or informal setting.
