What is the difference between Цесаре́вич and Царе́вич, please? Wikipedia seems to think that the former is only the heir to the throne and the latter any son of the Tsar, but it contradicts itself in other places.
Much obliged,
Simon
Answer Цесаре́вич - the heir to the throne before 1917
Царе́вич - any son of the Tsar
In which places does it contradict itself? Maybe I could help?
