Opening for French dad to embrace another Frenchman (8)
I believe the answer is:
premiere
'opening' is the definition.
(I've seen this before)
'french dad to embrace another frenchman' is the wordplay.
'french dad' becomes 'pere' ('father' in French).
'to embrace' means one lot of letters goes inside another.
'another frenchman' becomes 'remi' (I can't explain this - if you can you should believe this answer much more).
'pere' enclosing 'remi' is 'PREMIERE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for premiere that I've seen before include "Play's first public performance" , "First show" , "First screening" , "significant performance" , "Leading lady" .)
