Perform with energy on the French voyage (3,3)
I believe the answer is:
let rip
'perform with energy' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'on the french voyage' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'voyage' becomes 'trip' (I've seen this in another clue).
'le'+'trip' is 'LET RIP'.
Can you help me to learn more?
(Other definitions for let rip that I've seen before include "Speak violently - allow to tear" , "Speak without restraint" , "Express oneself angrily" , "Act violently" , "Release pent-up feelings" .)
