Sort of rifle nurse found on battleground (7)
I believe the answer is:
enfield
'sort of rifle' is the definition.
The definition suggests a singular noun which matches the answer.
'nurse found on battleground' is the wordplay.
'nurse' becomes 'EN' (abbreviation for enrolled nurse).
'found on' says to put letters next to each other.
'battleground' becomes 'field' (synonyms).
'en'+'field'='ENFIELD'
Can you help me to learn more?
(Other definitions for enfield that I've seen before include "Big centre" , "North London borough" , "NE London borough" , "Feel din of Kildare town" , "London suburb" .)
