Capital provided by a country's leader - endless stuff (5)
I believe the answer is:
accra
'capital' is the definition.
(capital of Ghana)
'a country's leader endless stuff' is the wordplay.
'a country's leader' becomes 'ac' (I am not sure about this - if you are sure you should believe this answer much more).
'endless' means to remove the last letter.
'stuff' becomes 'cram' (cramming is a kind of stuffing).
'cram' with its last letter taken off is 'cra'.
'ac'+'cra'='ACCRA'
'provided by' is the link.
Can you help me to learn more?
(Other definitions for accra that I've seen before include "African city" , "Ghana's capital" , "Largest city of Ghana" , "West African capital" , "foreign capital" .)
