A short way through unspoilt meadow (7)
I believe the answer is:
pasture
'meadow' is the definition.
(thesaurus)
'a short way through unspoilt' is the wordplay.
'a' becomes 'an'.
'short' means to remove the last letter.
'way' becomes 'st' (**).
'through' means one lot of letters goes inside another (I've seen this in other clues).
'unspoilt' becomes 'pure'.
'an' with its last letter taken away is 'a'.
'a'+'st'='ast'
'ast' put within 'pure' is 'PASTURE'.
(Other definitions for pasture that I've seen before include "Field suitable for grazing" , "Land for grazing cattle" , "Stock holder, perhaps" , "Meadowland" , "Meadow" .)
