Cultivate oregano on edge of allotment in the restricted zone
I believe the answer is:
no-go area
'the restricted zone' is the definition.
(I've seen this before)
'cultivate oregano on edge of allotment in' is the wordplay.
'cultivate' is an anagram indicator (I've seen 'cultivated' mean this).
'on' says to put letters next to each other.
'edge of allotment in' becomes 'a' (I am not sure about this - if you are sure you should believe this answer much more).
'oregano' with letters rearranged gives 'nogoare'.
'nogoare'+'a'='NO-GO AREA'
Can you help me to learn more?
(Other definitions for no-go area that I've seen before include "Place where entry is dangerous or forbidden" , "Dangerous territory" , "restricted zone" , "Zone where access is barred or risky" , "Place where entry is forbidden to, say, police" .)
