Director of a company at central Brixton (3)
I believe the answer is:
cox
'director' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'company at central brixton' is the wordplay.
'company' becomes 'co' (abbreviation).
'at' is a charade indicator (letters next to each other).
'central' means to look at the middle letters.
The middle letter of 'brixton' is 'x'.
'co'+'x'='COX'
'of a' acts as a link.
Can you help me to learn more?
(Other definitions for cox that I've seen before include "Member of rowing crew" , "Steerer of oarsmen in rowing boat" , "Helmsman" , "Steersman" , "Boat's steerer" .)
