Salesman drove off around Nunhead (6)
I believe the answer is:
vendor
'salesman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'drove off around nunhead' is the wordplay.
'off' is an anagram indicator.
'around' means one lot of letters goes inside another.
'nunhead' becomes 'n' (head letter of 'nun').
'drove' with letters rearranged gives 'vedor'.
'vedor' going around 'n' is 'VENDOR'.
Can you help me to learn more?
(Other definitions for vendor that I've seen before include "A Latin seller" , "Purveyor" , "Person who sells goods" , "who does business?" , "One selling house" .)
