• "In contrast, a root that shows a devoiced stop but which confuses the allophone with the homophonous phoneme should instead properly pair with another unvoiced stop."
• "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?)"
• "Internally *s has z as an allophone before voiced stops and possibly word finally."
