Great care to get Spain converted (5)
I believe the answer is:
pains
'great care' is the definition.
(I've seen this before)
'spain converted' is the wordplay.
'converted' indicates anagramming the letters.
'spain' with letters rearranged gives 'PAINS'.
'to get' acts as a link.
(Other definitions for pains that I've seen before include "Nice bakery's production" , "effort" , "Labour" , "Great care taken" , "Unpleasant feelings" .)
