The word "bosse" has its origin in the Old French word "bousse", which ultimately comes from the Latin word "bursa" meaning "bag" or "purse". This Latin word "bursa" gave rise to various derivatives and ended up evolving into "bosse" in Old French. Over time, "bosse" came to be used to refer to a swelling or lump, particularly one caused by a blow or injury, retaining a sense of containment or bag-like structure. In modern French, "bosse" still retains these meanings, and it can also refer to a bump or hump, both literally and metaphorically.
