'Yuvaraja' is the Sanskrit term for crown prince or heir apparent. 'Pattabhisegam' (or Pattabishekam) is the term for coronation or anointing ceremony. Therefore, 'Yuvaraja Pattabhisegam' specifically refers to the ceremony of anointing or crowning the heir apparent, which was a significant event in monarchies, including the Vijayanagar Empire.
