Fancy yard made to go wild (8)
I believe the answer is:
daydream
'fancy' is the definition.
(thesaurus)
'yard made to go wild' is the wordplay.
'to go wild' indicates anagramming the letters (a wild or chaotic ordering of the letters).
'yard'+'made'='yardmade'
'yardmade' is an anagram of 'DAYDREAM'.
(Other definitions for daydream that I've seen before include "Wool-gather" , "(Indulge in) idle reverie" , "Diurnal reveries" , "A pleasant diurnal fantasy" , "Distracting thoughts" .)
