Period of wild behaviour involving sheep and boy attendant (7)
I believe the answer is:
rampage
'period of wild behaviour' is the definition.
'rampage' can be an answer for 'behaviour' (I have seen 'destructive behaviour' mean 'rampage' so perhaps 'behaviour' could also mean 'rampage'). I'm unsure of the 'period of wild' bit.
'sheep and boy attendant' is the wordplay.
'sheep' becomes 'ram' (male sheep).
'and' is a charade indicator (letters next to each other).
'boy attendant' becomes 'page' (page can mean a boy servant).
'ram'+'page'='RAMPAGE'
'involving' is the link.
Can you help me to learn more?
(Other definitions for rampage that I've seen before include "Run amok" , "Dash around violently" , "Violent action" , "Charge around being wild and destructive" , "Storm" .)
