Swamp English boy cutting grass at the side of the road (9)
I believe the answer is:
everglade
'swamp' is the definition.
(thesaurus)
'english boy cutting grass at the side of the road' is the wordplay.
I cannot really understand how this works, but
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'boy' could be 'ade' and 'ade' is found within the answer.
'side' could be 'r' (abbreviation for right) and 'r' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for everglade that I've seen before include "nickname of US State" , "stretch of marshy grassland" , "Swamp (in Florida, e.g.)" .)
