It seems that the Gallo Italic, Italian, Neapolitan, Sicilian, Dalmatian, Romansch, Sardinian, Romanian, Venetian, Portuguese and Spanish have nothing in common but it seems that the languages were affected by the Justinian reconquests.
These languages seem to have something in common in their use of Con for the word With and Ab becomes A, in Occitan/Catalan they ambiguated Ab and Apud to Amb while French does have separate uses of Ab>A and Apud becomes Avec or Eut/Ot, Occitan simplified this further by merging Ab and Apud into Amb.
Does butterflying Justinian reconquests change the Spanish and Italian languages as a whole?
