Where nothing may be torn out (5)
I believe the answer is:
troon
'where' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'nothing may be torn out' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'may' is an anagram indicator (I've seen 'might' mean this (I've seen this in other clues)).
'out' means one lot of letters goes inside another.
'torn' anagrammed gives 'tron'.
'o' going within '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" .)
