Stall close to Spanish border (5)
I believe the answer is:
hedge
'stall' is the definition.
(I've seen this before)
'close to spanish border' is the wordplay.
'close to' indicates one should take the final letters (the close/ending of).
'border' becomes 'edge' ('edge' can be a synonym of 'border').
The last letter of 'spanish' is 'h'.
'h'+'edge'='HEDGE'
(Other definitions for hedge that I've seen before include "Row of bushes" , "Fence formed by bushes" , "Living barrier" , "Prevaricate; boundary" , "Barrier of shrubs or bushes" .)
