A Russian title for the heir to the throne or the son of a tsar, equivalent to 'prince' or 'crown prince' in other nations.
From Russian царевич (tsarevich), formed from tsar meaning 'emperor' plus -evich, a common Russian patronymic suffix meaning 'son of.' The term evolved to designate the imperial heir.
In Russian imperial history, being the tsarevitch was actually quite dangerous—there were so many power struggles that many heirs never made it to the throne, and some lost their lives in palace coups!
