### Etymology 1

From Middle Dutch schokken (“to push, jolt, shake, jerk”) or Middle French choquer (“to collide with, clash”), from Old Dutch *skokkan (“to shake up and down, shog”), from Proto-Germanic *skukkaną (“to move, shake, tremble”). Of uncertain origin. Perhaps related to Proto-Germanic *skakaną (“to shake, stir”), from Proto-Indo-European *(s)kek-, *(s)keg- (“to shake, stir”); see shake.
Cognate with Middle Low German schocken (“collide with, deliver a blow to, move back and forth”), Old High German scoc (“a jolt, swing”), Middle High German schocken (“to swing”) (German schaukeln), Old Norse skykkr (“vibration, surging motion”), Icelandic skykkjun (“tremulously”), Middle English schiggen (“to shake”). Doublet of shog.
