The region also has a form of another Latin named month in awi/ussu < augustus. This word does not appear to be a loan word through Arabic, and may have been taken over directly from Late Latin or African Romance. Scholars theorise that a Latin-based system provided forms such as awi/ussu and furar, with the system then mediating Latin/Romance names through Arabic for some month names during the Islamic period. The same situation exists for Maltese which mediated words from Italian, and retains both non-Italian forms such as awissu/awwissu and frar, and Italian forms such as april. Characteristics Starting from African Romance's similarity with Sardinian, scholars theorise that the similarity may be pinned down to specific phonological properties. Sardinian lacks palatization of velar stops before front vowels, and features the pairwise merger of short and long non-low vowels. Evidence is found that both isoglosses were present in African Latin (at least in the central province of Africa Proconsularis): Velar stops also remain unaffected in Latin loanwords in Berber. For example, tkilsit ("mulberry tree") < (morus) celsa in Latin, and i-kīkər ("chickpea") < cicer in Latin, or ig(e)r , ("field") < ager in Latin. Inscriptions from Tripolitania, written as late as the 10th or 11th century are written with a , diverging from contemporary European Latin uses. Thus, there are forms such as dikite ("say", 2nd person plural imperative), iaket ("he/she lies down"), dekember ("December") and pake ("peace") with such as dilektus ("beloved"), karus ("dear") and Afrikana ("African"), found in an inscriptional corpus. Some evidence that Latin words with a "v" are often written with a "b" in African Romance, as reported by Isidore of Seville: birtus ("virtue") < virtus in Latin, boluntas ("will") < voluntas, and bita ("life") < vita. Adams and Adamik both observe frequent b/v confusions in inscriptions and non-literary documents from Africa Proconsularis. On the other hand, according to Adamik Mauretania Caesariensis shows a much lower rate of betacism, comparable to Hispania or Gaul. The 5th century Albertini Tablets suggest high levels of phonetic errors and an uncertainty in the use of Latin cases. In a study of errors on stressed vowels in a corpus of 279 inscriptions, scholars noted how African inscriptions confused between over-stressed and under-stressed vowels between the 1st and 4th century AD, with Rome reaching comparable error rates only by the late 4th to 6th centuries. As aforementioned, there is strong evidence that
