 It is argued that the Mr or Mrs form of address is not compatible with the Malay naming system, probably due to the lack of family or surnames.It is therefore customary to address Malays using the Malay forms of address (Encik or Puan/Cik).A few Malay families do use surnames, such as Tengku, Megat, Nik, Wan, Raja and Che, which are passed down patrilineally, while others such as "Merican", "Khan" and "Munsi" indicate an Indian Muslim ancestry (since these names are Indian Muslim in origin).
