Flipped soldiers twice attack part supplier (7)
I believe the answer is:
caterer
'supplier' is the definition.
(a caterer supplies food)
'flipped soldiers twice attack part' is the wordplay.
I cannot really see how this works, but
'soldiers' could be 're' (Royal Engineers) and 're' is located in the answer.
'part' could be 'te' (te is a kind of part) and 'te' is present in the answer.
The remaining letters 'car' is a valid word 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 caterer that I've seen before include "Someone who provides food and service" , "One supplying needs" , "One providing food and service for a party" , "Provider of food and drinks" , "Provider of refreshments" .)
