More attempted root merging: *dhe:-/*do:- vs. *bhu:-

Suppose PIE *dhe:-/do:- <- PPIE *dhVw- (cf Slavic dav-) and
zero grade PPIE *dhw- -> PIE *bhw-?

That would mean:

PPPIE 3sg *-dhew-ti, 3pl *-dhw-énti ->
PPIE 3sg *-dhew-ti, 3pl *-bhw-énti

which could later be regularized either way:
PPIE 3sg *-dhew-ti, 3pl *-dhw-énti
or
PPIE 3sg *-bhew-ti, 3pl *-bhw-énti

One should take note of the fact that the roots *dhe:-, do:-, sta:-
etc as 'absolute' roots are probably derived from their 'conjunct'
counterparts (mostly it's the other way round), cf do:, dat with
condo:, condit; /a/ is 'reduced grade' here. That's why I wrote them
with preceding hyphen, before it there was a preverb.


(more likely it happened in the perfect:
PPPIE 3sg *-dhow-e, 3pl *-dhw-ér- ->
PPIE 3sg *-dhow-e, 3pl *-bhw-ér-

which could later be regularized either way:
PPIE 3sg *-dhow-e, 3pl *-dhw-ér-
or
PPIE 3sg *-bhow-e, 3pl *-bhw-ér-
)

I left out the reduplication syllable here,
it served as a placeholder for the preverb in the perfect.


Any counterexamples to *dhw- -> *bhw-?
