I fuss over woman in paddock (6)
I believe the answer is:
meadow
'paddock' is the definition.
(I've seen this before)
'i fuss over woman' is the wordplay.
'i' becomes 'me'.
'fuss' becomes 'ado' (synonyms).
'over' means one lot of letters go next to another.
'woman' becomes 'W' (abbreviation eg in Woman Police Constable).
'me'+'ado'+'w'='MEADOW'
'in' acts as a link.
(Other definitions for meadow that I've seen before include "somewhere grassy" , "A field of rich grass" , "Area used for hay" , "Tract of cultivated grassland" , "it's green here" .)
