Not to be confused with the French name Arnaud
Arnaut (Ottoman Turkish: آرناﺌود) is a Turkish term used to denote Albanians. In modern Turkish the term is used as Arnavut (pl. Arnavutlar).
As mercenary formations of the era were composed chiefly of Albanians the term took additional meaning like in the Danubian Principalities, where it was also used to denote various mercenary units. 
As a surname throughout the empire it spread in the forms of: al-Arnaut Arabic: أرنائوط (Arabic), Arnautović (Serbo-Croatian), Arnaoutis (Greek), Arnautov or Arnaudov (Bulgarian) and Arnăutu (Romanian).
