Field cut outside each day (6)
I believe the answer is:
meadow
'field' is the definition.
(a meadow is a field)
'cut outside each day' is the wordplay.
'cut' becomes 'mow' (as in mowing a lawn).
'outside' means one lot of letters goes inside another (some letters go outside others).
'each' becomes 'ea' (abbreviation).
'day' becomes 'd' (abbreviation for day).
'ea'+'d'='ead'
'mow' enclosing 'ead' is 'MEADOW'.
(Other definitions for meadow that I've seen before include "Lea" , "Low-lying grassland" , "A field of rich grass" , "A field of lush grass" , "Grassy field" .)
