means A flat, rigid or semi-rigid case with a handle, used for carrying clothes and belongings while travelling.

from A plain compound of "suit" plus "case," born in the age of rail and steamer travel — it was, quite literally, a case sized to hold a suit of clothes. "Suit" comes through Old French from Latin "sequi," to follow (a suit being a set of garments that go together, that "follow" one another), while "case" traces to Latin "capsa," a box or chest. So the word is two travellers themselves: a thing-that-matches packed inside a box-that-holds.
