concerning bóndi and bond:
i would be careful with gothic, this connection does not sound very logical
to me. gothic is a completely different branch of germanic languages, and
although they all share a common origin, they have developed in different
ways, especially concerning sound alternations in inherited words.
what is the original verb the participle ga-bundi comes from in gothic? i
think there's some mutation stuff in there (ablaut).
by the way in modern german we have the verb "bauen" (meaning to build, bu
probably related to bua originally) and a "bauer" is a farmer.
