Czesc Piotrze :)

Thanks for your help.
I'm unclear as to what happened in *lið-a- and *swaB-ja-:
*lið-a- < *leiþ-a- would be:
voicing of *þ - (root-final fricative in derivation) Verner's Law
*ei > *i: - why the short vowel?
*swaB-ja-
does it come directly from PIE or is it derived from PGmc *swef- ?
it would seem then that the same rule as above applies (Ringe 2006:
217)...
on the other hand *swop- > *swaB- also explains the vowel, so I'm
just wondering...
