Stick to African country - no borders (4)
I believe the answer is:
wand
'stick' is the definition.
(a wand is a small stick)
'african country no borders' is the wordplay.
I cannot really see how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found within the answer.
The remaining letters 'wad' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for wand that I've seen before include "Magic baton" , "Sorceror's magic stick" , "Magician's accessory" , "Magic rod?" , "Christmas tree fairy's rod" .)
