The chapter by Robert Crellin and Lucia Tamponi elucidates the vowel quality and quantity of Neo-Punic and Latin from North Africa and Sardinia. An important innovation presented in the article is the investigation not only of the representation of vowels in Neo-Punic by means of matres lectionis, but also of zero-representation and its relation to representation by matres lectionis. This sheds light on the degree of sensitivity of writers of Neo-Punic inscriptions to vowel length in Latin. The examination of the representation of vowel length and vowel quality further reveals that in both North Africa and Sardinia the distinction between /i, eː/ and /u, oː/ was retained despite the merger of these phonemes in Common Romance. The authors convincingly suggest that this is due to ties between North Africa and Sardinia. The article thus adds to our understanding of the linguistic development of both Romance and Punic in North Africa and Sardinia and to the relations between those two communities.
