Trains West African baboons (6)
I believe the answer is:
drills
This might be a double definition.
'trains west african' is the first definition.
'drills' can be an answer for 'trains' (drilling is a kind of training). I am not sure about the 'west african' bit.
'baboons' is the second definition.
(drill is a kind of baboon)
Can you help me to learn more?
(Other definitions for drills that I've seen before include "Boring tools" , "Bores in army exercises" , "Potato rows" , "they bore" , "Tools with a sharp points for making holes" .)
