Field for grazing (6)
I believe the answer is:
meadow
I believe this is a double definition.
'field' is the first definition.
(a meadow is a field)
'grazing' is the second definition.
(thesaurus)
'for' acts as a link.
(Other definitions for meadow that I've seen before include "Low-lying grassland" , "Lea" , "Grassed field" , "A field of rich grass" , "Field used for hay" .)
