Country contributing to Afghan appeal (5)
I believe the answer is:
ghana
'country' is the definition.
(I know that Ghana is a country)
'contributing to afghan appeal' is the wordplay.
'contributing to' says the answer is hidden in the clue (the answer contributes to part of the clue ).
'GHANA' can be found hidden inside 'afghan appeal'.
(Other definitions for ghana that I've seen before include "Ah, nag one into going to Africa" , "African country, W. of Togo" , "West African country getting independence from the UK in 1957" , "West African country, independent since 1957" , "W. African state" .)
