Baggage is another word for the bags you put your stuff in when you travel. It’s also known as "luggage" or "suitcases." If someone says you have baggage but you’re not holding anything, they’re talking about emotional baggage.
Baggage is the fancy suitcase you collect from an airport carousel or the duffel bag you get out of the trunk. It’s any travel bag you have your personal belongings in. Baggage can also refer to emotions from the past that get in the way of the present. In military terminology, baggage is any equipment that can be carried or hauled along. This is the original definition, from the Old French baggage, "military equipment," from bague, for "bag or bundle."
