sag

sag: [15] There are several Scandinavian verbs that bear a strong resemblance to sag, including Swedish sacka and Danish sakke, and it seems likely that one of these was borrowed into Middle Low German as sacken ‘settle, subside’, and subsequently found its way into English as sag (whose original meaning was ‘subside’)

sag (v.)

late 14c., possibly from a Scandinavian source related to Old Norse sokkva "to sink," or from Middle Low German sacken "to settle, sink" (as dregs in wine), from denasalized derivative of Proto-Germanic base *senkwanan "to sink" (see sink (v.)). A general North Sea Germanic word (compare Dutch zakken, Swedish sacka, Danish sakke). Of body parts from 1560s; of clothes from 1590s. Related: Sagged; sagging.

sag (n.)

1580s, in nautical use, from sag (v.). From 1727 of landforms; 1861 of wires, cables, etc.
