n. a small piece of luggage that can be taken onto an airplane as hand luggage

The term "carry-on" emerged in the mid-20th century with the rise of commercial air travel. It combines "carry" (from Old Northern French carier, meaning "to transport") and "on" (Old English on, indicating continuation). Originally describing luggage small enough to be carried aboard, it later gained figurative use for persistent issues. The morphemes reflect both physical action ("carry") and the concept of continuity ("on").
