The terrorists twice gave mum a turn (3,3)
I believe the answer is:
mau mau
'turn' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'the terrorists twice gave mum a' is the wordplay.
I cannot really understand how this works, but
'mum' could be 'ma' (both can mean mother) and 'ma' is found within the answer.
'a' is present in the answer.
The remaining letters 'umu' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mau mau that I've seen before include "Kenyan activists" , "Kenyan terrorist group" , "movement in Africa" .)
