sø:fa) is archaic, residual and anything _but_ productive in Germanic,

Grand, thank you.

What about fientive verbs? If we consider:
*þurzna- < the causative *þers-a-
*lizna- < the causative *laiz-i- (or PIE *lais-???)
Is it likewise the (SV3) zero grade/the Gmc. (WV1) preterite?
What sort of formative suffix was added after *-na-?
Would they both be Gmc innovations?

And a separate question:
*/leb-/ > OE lippa
*/spr-/ > OE spre:awlian
What would be the Gmc stage?
