When on holiday the French really go for it! (3,3)
I believe the answer is:
let rip
'go for it' is the definition.
'when on holiday the french really' is the wordplay.
I cannot quite see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'holiday' could be 'trip' (I've seen this before) and 'trip' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for let rip that I've seen before include "Behave uninhibitedly" , "Express oneself angrily" , "Proceed unrestrained" , "Hasten" , "Talk aggressively" .)
