1590s, from lug (v.) "to drag" + -age; so, literally "what has to be lugged about" (or, in Johnson's definition, "any thing of more weight than value"). In 20c., the usual British word for "baggage belonging to passengers."
word-forming element in nouns of act, process, function, condition, from Old French and French -age, from Late Latin -aticum "belonging to, related to," originally neuter adjectival suffix, from PIE *-at- (source of Latin -atus, past participle suffix of verbs of the first conjugation) + *-(i)ko-, secondary suffix forming adjectives (see -ic).
mid-15c., "portable equipment of an army; plunder, loot," from Old French bagage "baggage, (military) equipment" (14c.), from bague "pack, bundle, sack," probably ultimately from the same Scandinavian source that yielded bag (n.). Later used of the bags, trunks, packages, etc., of a traveler (in this sense British English historically prefers luggage). Baggage-smasher (1847) was American English slang for "railway porter."
Used disparagingly, "worthless woman, strumpet" from 1590s; sometimes also playfully, "saucy or flirtatious woman" (1670s). Emotional baggage "detrimental unresolved feelings and issues from past experiences" is attested by 1957.
