wurde

Etymology
Formed by analogy with the plural, from (singular ). The verbs of this class normally generalise the singular vowel; as in etc. we should thus expect. These forms are attested, but the plural usually retained the u-form and this -u- tended to be generalised to the singular. A possible reason is the a-forms’ phonetic similarity to. The final -e in is unetymological; it goes back to a development in Early Modern German where -e was added to strong past tenses (after the subjunctive and/or by hypercorrection; hence archaic  for ). It may have survived here by analogy with the fellow auxiliary.
