The verb may be regarded as an iterative or emphatic form of waian waw, verb, which is often nearly synonymous; it was used, e.g., of a loose tooth. Parallel formations from the same root are the Old Norse vagga feminine, cradle (Swedish vagga, Dutch vugge), Swedish vagga (“to rock a cradle"), early modern German waggen (dialectal German wacken) to waver, totter. Compare waggle, verb
