Gad about with nurse and actor in part of London (8)
I believe the answer is:
dagenham
'part of london' is the definition.
The definition suggests a singular noun which matches the answer.
'gad about with nurse and actor' is the wordplay.
'about' says the letters should be written backwards.
'with' says to put letters next to each other.
'nurse' becomes 'en' (abbreviation for enrolled nurse).
'and' is a charade indicator (letters next to each other).
'actor' becomes 'ham' (ham is a kind of actor).
'gad' in reverse letter order is 'dag'.
'dag'+'en'+'ham'='DAGENHAM'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for dagenham that I've seen before include "Eastern area in Greater London" , "In car manufacturing centre" , "Area of east London" , "Barking and -, London borough" , "Essex town" .)
