Locally, treat roughly my group found in The Hill going all the way back (5)
I believe the answer is:
roust
'back' is the definition.
Both the definition and answer are verbs in their base form.
Perhaps they are linked in a way I don't understand?
'locally treat roughly my group found in the hill going all the way' is the wordplay.
I cannot really understand how this works, but
'group' could be 'o' (O is an example) and 'o' is found within the answer.
'way' could be 'st' and 'st' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for roust that I've seen before include "Get out of bed maybe" , "Create stir" , "Root out" , "Stir up (mainly US)" , "Wake up" .)
