Did you Know?
There are many words similar to “silt” across northern European languages. In Norwegian and Dutch the word “sylt” refers specifically to a “salt marsh,” as does the word “sylta” in Swedish. These words were preceded by the Middle Low German “sulte,” also meaning “salt-marsh.” All are related to the Old English “sealt” (circa 11th century) meaning “salt.” Between the 15th and 16th century, “silt” developed its modern meaning of fine sediment deposited by water.
