Fish seen by boat that may be multi-storey? (3,4)
I believe the answer is:
car park
'fish seen by boat that may be multi-storey?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'fish seen by boat' is the wordplay.
'fish' becomes 'carp' (carp is a kind of fish).
'seen by' is a charade indicator (letters next to each other).
'boat' becomes 'ark' (ark is a kind of boat).
'carp'+'ark'='CAR PARK'
Can you help me to learn more?
(Other definitions for car park that I've seen before include "multistorey, for example - with 27d" , "Where vehicles are left" , "Place to leave vehicles" , "Multi-storey building with bays" , "Area for transport (in which one goes into space)" .)
