Hopeful lady (4)
I believe the answer is:
rosy
I believe this is a double definition.
'hopeful' is the first definition.
('rosy' can be a synonym of 'hopeful')
'lady' is the second definition.
(I've seen this before)
(Other definitions for rosy that I've seen before include "lady" , "Blushing - optimistic" , "Promising; hopeful" , "Hopeful; blushing" , "Blooming - hopeful" .)
