Each day coming in to cut field (6)
I believe the answer is:
meadow
'field' is the definition.
(thesaurus)
'each day coming in to cut' is the wordplay.
'each' becomes 'ea'.
'day' becomes 'd'.
'coming in to' is an insertion indicator.
'cut' becomes 'mow' (mowing is a kind of cutting**).
'ea'+'d'='ead'
'ead' put inside 'mow' is 'MEADOW'.
(Other definitions for meadow that I've seen before include "Seventeen dn used for hay" , "area of grassland" , "Field used for hay" , "In rural location" , "Paddock" .)
