Under new African organisation Spain gets resolution (9)
I believe the answer is:
endurance
'resolution' is the definition.
(thesaurus)
'under new african organisation spain' is the wordplay.
'new' indicates anagramming the letters.
'african organisation' becomes 'anc' (I've seen this in other clues).
'spain' becomes 'e' (abbreviation for Espana).
'under' anagrammed gives 'endur'.
'endur'+'anc'+'e'='ENDURANCE'
'gets' is the link.
(Other definitions for endurance that I've seen before include "Showing ablity to last" , "Patient toleration" , "Polar ship" , "Crude Anne (anag.)" , "Patient suffering" .)
