Get African country heard? (6)
I believe the answer is:
'get' is the definition.
(I know that garner is a more specific form of the action get)
'african country heard?' is the wordplay.
'african country' becomes 'Ghana' (country in Africa).
'heard?' indicates a 'sounds like' (homophone) clue.
'ghana' sounds like 'GARNER'.
(Other definitions for garner that I've seen before include "Gather, earn" , "Collect from ranger" , "Store up; Erroll ---, jazz pianist" , "Collect and store" , "Gather or collect" .)
