Roses pined terribly for the blues (10)
I believe the answer is:
depression
'blues' is the definition.
(I've seen this before)
'roses pined terribly' is the wordplay.
'terribly' indicates anagramming the letters.
'roses'+'pined'='rosespined'
'rosespined' with letters rearranged gives 'DEPRESSION'.
'for the' acts as a link.
(Other definitions for depression that I've seen before include "mental anguish" , "Bad times" , "Blues" , "valley" , "Nineteen twenty nine financial slump" .)
