Etymology Exact origin unknown. The earliest recorded reference for the noun was to heavy, useless objects such as old, discarded furniture. Perhaps from the verb lumber in reference to meaning "awkward to move"; Online Etymological Dictionary thinks this may derive from the same root as lame. Possibly influenced by Lumbar, an obsolete variant of Lombard, the Italian immigrant class known for being pawnbrokers and money-lenders in early England. Compare English lumpish.
