Parking was to be found for Candida, perhaps (4)
I believe the answer is:
play
'candida perhaps' is the definition.
(Candida is a play by George Bernard Shaw)
'parking was to be found' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'was to be found' becomes 'lay' (as in a building laying in a certain area).
'p'+'lay'='PLAY'
'for' acts as a link.
(Other definitions for play that I've seen before include "Hamlet, for example" , "Participate in games or sport" , "Theatre production" , "Theatrical production" , "Stage drama" .)
