>Wasn't final <d> v. final <t> the reflection of a phonetic distinction? At some stage we seem to have final V:d > V: (attested in writing, notably for the ablative singular) but final V:t > Vt (3s of verbs).
> Evidently, Latin was like German and Russian and pronounced all final syllables unvoiced.
