Ratu

''Ratu'' () is an Austronesian title used by male Fijians of chiefly rank. An equivalent title, ''adi'' (pronounced ), is used by females of chiefly rank. In the Malay language, the title ''ratu'' is also the traditional honorific title to refer to the ruling king or queen in Javanese culture (though it has since been used in modern contexts to refer to both queen regnant and queen consort of any nation, e.g. "Ratu Elizabeth II" and "Ratu Camilla"). Thus in Java, a royal palace is called "''keraton''", constructed from the circumfix ''ke- -an'' and ''Ratu'', to describe the residence of the ratu.

Ratu: A chiefly title for men used alone as a form of address, or in front of the chief's name, only in certain places The source of the Fijian title is Verata, and it has spread throughout Fiji during the past century, now applied to many local, minor chiefs as well as the major ones. The concept of his type of title is from Tonga. Strictly speaking, the title belongs only in Verata. In their time, Cakobau or Tanoa, his father, never themselves used the title of Ratu. It does not appear with Cakobau's name or any other chief's name in the Deed of Cession of 1874. (Exceptionally, in the 1850s, Ratu Mara Kapaiwai was one of the few who did use the word Ratu, though that may have been a name rather than a title.) It has been affixed to the names of Tana and Cakobau by later Fijians, retroactively. The Cakobau Memorial Church on Bau Island is now referred to as the Ratu Cakobau Church. Ratu may also be used as a personal first name or second name. The title may be acquired as part of a chiefly name, by a namesake. In such cases, it does not imply chiefly status. Adi is the female equivalent, sometimes heard as Yadi in Lau. Provided by Wikipedia
