Hindu PA becomes French royal (7)

I believe the answer is:

dauphin

I'm a little stuck... Click here to teach me more about this clue!

'french royal' is the definition.
'dauphin' can be an answer for 'royal' (dauphin is a kind of royal). I'm unsure of the 'french' bit.

'hindu pa becomes' is the wordplay.
'becomes' is an anagram indicator.
'hindu'+'pa'='hindupa'
'hindupa' with letters rearranged gives 'DAUPHIN'.

Can you help me to learn more?

(Other definitions for dauphin that I've seen before include "Eldest son of the French king" , "French king's eldest son" , "King of France's heir" , "Formerly, the eldest son of the King of France" , "French royal heir" .)
