I suspect the Polynesians stole the A's. And the French sure seem to have a suspicious surplus of E's and U's. But it's likely the French stole their vowels from the Poles and Czech's, who then became so desperate that they pressed "Z" into service.

I suggest DNA testing of words around the world to determine where the missing Welsh vowels went.

I suggest DNA testing of words around the world to determine where the missing Welsh vowels went.

There's only one vowel in "DNA". Besides, the Welsh seem to make do with the "sometimes y and w" clause.
