A youngest son from African country going round block (8)
I believe the answer is:
benjamin
'a youngest son' is the definition.
'benjamin' can be an answer for 'son' (I have seen 'Son of Jacob ' mean 'benjamin' so perhaps 'son' could also mean 'benjamin'). I'm not sure about the 'a youngest' bit.
'african country going round block' is the wordplay.
'african country' becomes 'benin' (Benin is an example).
'going round' indicates putting letters inside.
'block' becomes 'jam' (synonyms).
'benin' enclosing 'jam' is 'BENJAMIN'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for benjamin that I've seen before include "British composer of 'Peter Grimes'" , "Jacob's youngest son" , "ancient tribe" , "Boy" , "tribal leader" .)
