"The heavy suitcase and backpack filled up most of my luggage compartment, leaving little room for other baggage."
Usage: Avoid using the singular form "a baggage" to refer to luggage; use "baggage" as an uncountable noun even when referring to a single item. Do not confuse it with "luggage," which is interchangeable in most contexts but slightly more common in British English.
The word baggage comes from Middle English and Old French terms for a bundle or sack, which ultimately trace back to Germanic roots related to carrying packs. While it originally referred simply to luggage, its modern meaning expanded to include the personal belongings of soldiers before evolving further in usage.
