词源
From late Middle English saggen, probably of North Germanic/Scandinavian/Old Norse origin, akin to Old Norse sokkva (“to sink”), from a denasalized derivative of Proto-Germanic *sinkwaną (“to sink”). Compare Norwegian Nynorsk sagga (“move slowly”)); probably akin to Danish and Norwegian sakke, Swedish sacka, Icelandic sakka. Compare also Dutch zakken and German sacken (from Low German).
