Sheep annually moving back for example, rush about wildly (7)
I believe the answer is:
rampage
'rush about wildly' is the definition.
(I've seen this before)
'sheep annually moving back for example' is the wordplay.
'sheep' becomes 'ram' (ram is a kind of sheep).
'annually' becomes 'pa' ('p.a.' can be a synonym of 'annually').
'moving back' says the letters should be written in reverse.
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'eg' in reverse letter order is 'ge'.
'ram'+'pa'+'ge'='RAMPAGE'
(Other definitions for rampage that I've seen before include "Rage wildly around" , "Rioting, for example" , "destructive behaviour" , "Fury" , "Rush around violently and uncontrollably" .)
