Origin

From line (verb: to cover the inside of, from Old French liner, from lin — flax, linen) + -ing (the suffix forming verbal nouns and gerunds). The verb to line meaning to cover the inside was originally about covering with linen — the first linings being linen fabric on the inside of garments. Used in English from the 14th century.
