There seem to be a number of roots with final laryngeal that also show forms
with -i- (not counting the obvious Sanskrit i < vocalic H). They appear in
Pokorny with -(i) at the end. Piotr has suggested a reduction of an
original diphthong, but that explains the variation -euH/-eH and -eiH/-eH,
not the sequence -Hi. Besides, it is an i that pops up so unexpectedly in
these words, not u.
I don't know of any discussion of this. Any ideas?
