So far, I'm thinking that gemination was merely an allophonic variation of non-geminated phonemes.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

But neither is gemination - your comparision points from Danish involve a preceding stressed vowel.    From Wordnik.com.  [Precising on a new rule to explain Pre-IE word-final voicing] Reference

I've also thought of a good reason why secondary stress would be insufficient in explaining this gemination.    From Wordnik.com.  [Archive 2008-07-01] Reference

In the rule I'm now proposing for Pre-IE, I suggest that this same gemination occurs, but only in unstressed syllables.    From Wordnik.com.  [Archive 2008-07-01] Reference

Wait, I realize now having misunderstood somewhat; you're not trying to trigger gemination by apocope, but by reduction.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

Maybe so, but the example shows that gemination may occur in unstressed positions while stressed positions may avoid it.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

The reduction or deletion of a word-final vowel with simultaneous gemination of the preceding consonant is commonplace e.g.    From Wordnik.com.  [Archive 2008-07-01] Reference

If the gemination is compensatory lengthening which I'd expect it to be, reduction and gemination were in fact simultaneous.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

The gemination would require a preceding unstressed vowel and it would also require that the vowel after the consonant be a supershort schwa.    From Wordnik.com.  [Precising on a new rule to explain Pre-IE word-final voicing] Reference

I'd suggest direct insertion of a glottal stop, rather than gemination, except that's not really a process associated with an unstressed position.    From Wordnik.com.  [Precising on a new rule to explain Pre-IE word-final voicing] Reference

An inconvenience about taking your precedents from Germanic is that the origins of stød & gemination are far from clear-cut, and intertwined with PIE itself.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference

I've never seen Japanese described as an example of this kind of compensatory gemination after all, the coda consonant /N/ is moraic, but rather as an example of vowel devoicing.    From Wordnik.com.  [A few more words on my new Gemination rule for Pre-IE] Reference
