One description of the river's naming was recorded in 1945 by
George R. Stewart, but is now considered to be a folk tale: Dick Carter, Chair of the Delaware Heritage Commission, states that the name of Murderkill River is taken from the original Dutch for Mother River. Mother is
moeder in
Middle Dutch, and river is
Kille. Later, under British rule, the word "River" was added to the waterway's name, effectively making it "mother river river." Delaware's creeks and rivers are slow-moving and there is deep mud associated with marshy rivers. Dutch "modder" = mud, a false cognate to "mother." Modder Kill = Muddy Creek or Muddy River. The word is still used in Dutch, such as this Dutch video of a tractor stuck in mud ("vast in de modder"). Also, in New York there is
Muddy Kill, with a clear connection to the older Dutch name. == Variant names ==
