- silt
- c.1440, originally "sediment deposited by seawater," probably from M.L.G. or M.Du. silte, sulte "salt marsh, brine," related to O.E. sealt, O.H.G. sulza "saltwater," Ger. Sulze "brine" (see salt). The verb meaning "to become choked with silt" (of river channels, harbors, etc.) is attested from 1799.
