Tautosyllabic

Having not thought deeply about PIE's curious phonotactic constraint that barred the tautosyllabic cooccurence of both a voiced aspirated stop such as *dh with a voiceless stop such as *t in a root, I've had no good explanation for it up to now. ❋ Unknown (2009)

If one thinks of these roots on both the phonemic and phonetic levels, then one understands the resultant phonetic t(ʰ) as merely an allophone of *dʰ following *s (or perhaps more specifically tautosyllabic *s?) ❋ Unknown (2009)

Can we not just say that it demands that the sounds are adjacent and tautosyllabic before the law can operate? ❋ Unknown (2009)

Can you cite a word with an instance of an adjacent, tautosyllabic combination of sibilant plus aspirate stop where we know that Siebs' Law cannot apply? ❋ Unknown (2009)

No Semitic loans identified during this period seem to require tautosyllabic consonant clustering in Mid IE either. ❋ Unknown (2009)

Now, this is a matter of detail perhaps but worth noting since p has occasionally eroded to f in Etruscan, particularly next to tautosyllabic u, and this sort of lenition can only rationally happen with a bilabial phoneme, not a labiodental one. ❋ Unknown (2009)

To pursue this end, I'd recommend explaining the rules behind this alleged preaspiration, particularly since in your example [j] and [tʰ] are not tautosyllabic. ❋ Unknown (2009)

The f in this lexeme is merely lenition of p neighbouring tautosyllabic u, particularly when the next syllable contains a front vowel. ❋ Unknown (2009)

Afterall, these affected consonants are nearer to the eventually-omitted tautosyllabic schwa than an accented vowel in a preceding syllable. ❋ Unknown (2008)

For example, I reason that MIE *ʔékwa- "horse" and *kérna "horn" would likely have resisted Syncope because *kw and *rn wouldn't have been valid syllable codae in early Late IE, the former violating sonority hierarchy and the latter showing adjacent tautosyllabic resonants which would have offended language-specific phonotactic restrictions at the time. ❋ Unknown (2008)

Many instances of f seem to be attributable to earlier p neighbouring tautosyllabic u but it doesn't explain all instances. ❋ Unknown (2008)
