Where nothing may be torn out (5)
I believe the answer is:
troon
'where' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'nothing may be torn out' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'may be' indicates anagramming the letters.
'out' is an insertion indicator.
'torn' is an anagram of 'tron'.
'o' going into 'tron' is 'TROON'.
Can you help me to learn more?
(Other definitions for troon that I've seen before include "A royal Scottish golf club" , "Coastal town of West Scotland" , "Scottish golf town" , "Ayrshire golf course" , "Clyde port" .)
