Carnival in the car park? (6)
I believe the answer is:
fiesta
'carnival' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fiesta that I've seen before include "A Spanish public celebration" , "(Spanish) religious festival" , "celebration abroad" , "Elaborate public party, in Spain perhaps" , "Spanish holiday" .)
