Drink with old women in field (6)
I believe the answer is:
meadow
'field' is the definition.
(a meadow is a field)
'drink with old women' is the wordplay.
'drink' becomes 'mead' (mead is a kind of drink).
'with' is a charade indicator (letters next to each other).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'women' becomes 'w'.
'mead'+'o'+'w'='MEADOW'
'in' acts as a link.
(Other definitions for meadow that I've seen before include "Grassed field" , "Area used for hay" , "In rural location" , "Tract of cultivated grassland" , "area of grassland" .)
