Visionary feature made Yard remarkable (8)
I believe the answer is:
daydream
'visionary feature' is the definition.
(daydream is a kind of vision)
'made yard remarkable' is the wordplay.
'remarkable' indicates an anagram.
'made'+'yard'='madeyard'
'madeyard' is an anagram of 'DAYDREAM'.
(Other definitions for daydream that I've seen before include "An idle diurnal fantasy" , "Diurnal reverie" , "A pleasant diurnal fantasy" , "Wool-gather" , "Indulge in a fantasy" .)
