Enjoyed unacceptable shelter by side of pitch (6)
I believe the answer is:
dugout
'shelter by side of pitch' is the definition.
'dugout' can be an answer for 'shelter' (I've seen this before). I'm unsure of the 'by side of pitch' bit.
'enjoyed unacceptable' is the wordplay.
'enjoyed' becomes 'dug' (slang).
'unacceptable' becomes 'out' (out can mean incorrect or inappropriate).
'dug'+'out'='DUGOUT'
Can you help me to learn more?
(Other definitions for dugout that I've seen before include "Type of canoe" , "Simple craft" , "Soldier's trench" , "Rough shelter" , "Military shelter" .)
