The word "zaino" has multiple origins depending on the context. In Spanish, it is derived from the Latin word "sagma" or "saccus", which refer to a large bag or pack. This Latin term was later adapted into the Old Spanish word "caino" or "zaíno", which originally meant a horse with black or dark brown hair. Over time, the meaning of "zaíno" expanded to include any dark-colored animal or object.
However, in Italian, the word "zaino" has a different origin. It comes from the Late Latin word "zanellus", which means a small, rustic, and durable backpack. This term was then modified into "zan(i)ellus" in medieval Italian, eventually evolving into "zaino" to refer to a backpack used by soldiers or travelers.
