Musti is typical of Barletta (BA), Musto is typical of Campania, Mustu is practically unique, it is difficult to identify the origin of these surnames, the hypothesis of the derivation from the Arabic name Mushtaaq is unlikely although not impossible. additions provided by Stefano Ferrazzi Musto is typically from Campania, with a secondary lineage in the Bari area, while Musti, much more rare, comes from Barletta (BA), both of these surnames should derive from the dialectal term mustu (from the Latin mustum), with the meaning of must, most probably indicating the activity of winemaker or wine producer. It is therefore a question of the surnames of trade names attributed to the founders.
