Etymology
From Middle English synken, from Old English sincan, from Proto-West Germanic *sinkwan, from Proto-Germanic *sinkwaną, from Proto-Indo-European *sengʷ- (“to fall, sink”). Compare West Frisian sinke, Low German sinken, Dutch zinken, German sinken, Danish and Norwegian Bokmål synke, Swedish sjunka. In the causative sense, it replaced Old English senċan (“make sink”) from Proto-Germanic *sankwijaną.
