Give up drifting idly around Spain (5)
I believe the answer is:
yield
'give up' is the definition.
(I've seen this before)
'drifting idly around spain' is the wordplay.
'drifting' indicates an anagram.
'around' is an insertion indicator.
'spain' becomes 'e' (abbreviation for Espana).
'idly' is an anagram of 'yild'.
'yild' going around 'e' is 'YIELD'.
(Other definitions for yield that I've seen before include "Chicken out" , "Surrenders or bears as a crop" , "Give forth" , "Surrende, give in" , "return of financial investment" .)
