Long story about Spain (5)
I believe the answer is:
yearn
'long' is the definition.
('yearn' can be a synonym of 'long')
'story about spain' is the wordplay.
'story' becomes 'yarn' ('yarn' can be a synonym of 'story').
'about' indicates putting letters inside.
'spain' becomes 'e' (abbreviation for Espana).
'yarn' going around 'e' is 'YEARN'.
(Other definitions for yearn that I've seen before include "Have strong desire" , "Mark of injury" , "Desire, want" , "Feel desire" , "Long - pine" .)
