The tomorrow that never comes (6)
I believe the answer is:
manana
'the tomorrow' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for manana that I've seen before include "Sharply-defined" , "Contrapuntal musical composition" , "Tomorrow in Cadiz" , "Tomorrow in Barcelona" , "Some indefinite time in the future (Spanish)" .)
