An Aberdonian perhaps in Berkshire location (5)
I believe the answer is:
ascot
'in berkshire location' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'an aberdonian' is the wordplay.
'an' becomes 'a'.
'aberdonian' becomes 'scot' (I've seen this in another clue).
'a'+'scot'='ASCOT'
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for ascot that I've seen before include "English course" , "Berkshire town, famous for horse racing" , "Royal race meeting venue" , "Necktie with wide square ends" , "Where ladies wear new hats" .)
