Ratu is a feminine Indonesian name that means "queen" in the Indonesian and Malay languages.In the Malay language, the word ratu is traditionally an honorific title for a ruling king or queen in Javanese culture. The term has been adopted in modern Indonesian and Malay to denote a queen regnant or queen consort, such as in the phrases "Ratu Elizabeth II" and "Ratu Camilla". Etymologically, it is connected to the Austronesian root *datu meaning "chieftain" or "elder", found in various forms across the region (cf. Datu in the Philippines, datuk in Malay).Cultural SignificanceIn Javanese culture, the term ratu is deeply embedded in traditional governance and royal courts. A royal palace is called keraton, derived from the circumfix ke- -an and the word ratu, meaning "the residence of the ratu". The usage of the title spread beyond Java; according to Wikipedia, the Fijian chiefly title Ratu (pronounced [ˈrɑːtu]) is also derived from the same Austronesian root, though the Fijian form is used exclusively for male chiefs, with the female equivalent being adi.However, this article concerns the Indonesian feminine given name Ratu, which directly borrows the word meaning "queen". It is a relatively modern usage, typical of Indonesian naming practices that incorporate titles, positive qualities, or majestic terms from the national language.Meaning: queenOrigin: Austronesian (Malay/Javanese)Type: given nameUsage: Indonesian
