Origin & History of “sink”

Sink is a general Germanic verb, with relatives in German sinken, Dutch zinken, Swedish sjunka, and Danish synke. But where their common Germanic ancestor came from is not known. these days, sink means both ‘go below water’ and ‘cause to go below water’, but originally it was used only for the former. there was a separate but closely related verb, sench, for ‘cause to sink’, which died out in the 14th century. The noun sink (15th c.) originally denoted a pit ‘sunk’ in the ground for receiving water.
