Sardinian phonology

This meant that the difference between [ɛ ɔ] and [e o] had achieved phonemic status, giving Campidanese a total of seven distinct vowels, as opposed to the older five-vowel system retained by other Sardinian dialects.

All plosives participate in a system-wide and complex process of lenition that characterizes all varieties of Sardinian and operates across word boundaries.

The Campidanese dialect does not generally allow this /R/ to end syllables except if followed by another /R/; as a result, underlying /R.C/ sequences are synchronically and systematically repaired, either through assimilation or metathesis:[19][22] Lenition occurs in intervocalic position.

For Nuorese, /s/ and /r/ neutralise (merge) when in sandhi in the following way:[16][22] The word-final /t/ is assimilated to the following consonant within a phrase, or can be said to disappear, inducing strengthening: Log.

Special cases: Unlike Tuscan Italian, Neapolitan and Sicilian, Sardinian doesn't have a productive process of syntactic gemination since most Latin final consonants have been maintained.
