Don’t allow to poke in the stick (5)
I believe the answer is:
baton
'the stick' is the definition.
(term for a stick or staff)
'don't allow to poke' is the wordplay.
I cannot really see how this works, but
'to' is present in the answer.
'don't allow' could be 'ban' (I've seen this in another clue) and 'ban' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for baton that I've seen before include "one watched by players" , "Stick passed in relay races" , "Conductor's rod" , "Short stick" , "Conductor wields it - or a policeman" .)
