Ghost consonants in Italian and Brabantian

Two of my favourite languages have something you could call ghost consonants. In Italian and Brabantian, consonants that were lost long ago still have an effect in the modern language. To illustrate how this works, I made a video. It first tells you about the Italian ghost consonants and then turns to the native language of my grandparents, Central Brabantian, a regional language spoken in the Netherlands. Do you know other languages that have ghost consonants? Let me know!
