Shoots back around ring to submit (5)
I believe the answer is:
stoop
'shoots back' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'around ring to submit' is the wordplay.
'around' is an insertion indicator.
'ring' becomes 'o' (letter resembling a ring).
'to submit' becomes 'stop' (I am not sure about this - if you are sure you should believe this answer much more).
'o' inserted into 'stop' is 'STOOP'.
Can you help me to learn more?
(Other definitions for stoop that I've seen before include "Bow or bend" , "Lower one's standards" , "go on a bender?" , "Hunch" , "Stand bent forward" .)
