Stick at your task of not getting out! (5)
I believe the answer is:
baton
'your task of not getting out' is the definition.
I can't judge whether this definition defines the answer.
'stick at' is the wordplay.
'stick' becomes 'bat' (bat is a kind of stick**).
'at' becomes 'on' (location).
'bat'+'on'='BATON'
Can you help me to learn more?
(Other definitions for baton that I've seen before include "Short stick" , "It's used by a conductor and a policeman" , "Stick passed in relay races" , "weapon" , "Conductor wields it - or a policeman" .)
