Where to make some arrangement about parking (5)
I believe the answer is:
epsom
'where to' is the definition.
The definition suggests a singular noun which matches the answer.
'some arrangement about parking' is the wordplay.
'arrangement' indicates an anagram.
'about' is an insertion indicator.
'parking' becomes 'p'.
'some' with letters rearranged gives 'esom'.
'esom' placed around 'p' is 'EPSOM'.
'make' is the link.
Can you help me to learn more?
(Other definitions for epsom that I've seen before include "Racecourse near London" , "Racetrack" , "Home to the Derby and the Oaks" , "Home to the Derby and the Oakes" , "Derby course" .)
