Etymology

From Old English wundor, a noun for marvel or miracle, descended through Proto-West Germanic wundr and Proto-Germanic wundrą. The cognates spread across the Germanic languages: Dutch wonder, German Wunder, Danish, Norwegian and Swedish under, Icelandic undur, and Scots wunner.

The verb follows a parallel track. Old English wundrian, from Proto-Germanic wundrōną, yielded Middle English wondren. The same root produced Saterland Frisian wunnerje, West Frisian wûnderje, Dutch wonderen, Low German wunnern, German wundern, Swedish undra, and Icelandic undra.

A distant PIE cognate survives in English wish.
