Satisfactory opening in Africa? Very good for African mammal (5)
I believe the answer is:
okapi
'african mammal' is the definition.
(I've seen this in another clue)
'satisfactory opening in africa? very good' is the wordplay.
'satisfactory' becomes 'ok' (similar in meaning).
'opening in' says to take the initial letters.
'very good' becomes 'pi' (old-fashioned slang for pious).
The initial letter of 'africa' is 'a'.
'ok'+'a'+'pi'='OKAPI'
'for' is the link.
(Other definitions for okapi that I've seen before include "Wild animal" , "browser" , "Hoofed mammal" , "Rare mammal" , "rainforest ruminant" .)
