The end of Spain? It's delicate (5)
I believe the answer is:
elfin
'delicate' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
(Other definitions for elfin that I've seen before include "Small and delicate like fairy" , "Small, delicately-framed" , "Like a tiny fairy" , "Small, delicate, mischievous and attractive" , "Describing Santa's helpers" .)
