Form of security in one complex protecting underground chamber (10)
I believe the answer is:
encryption
'form of security' is the definition.
The definition suggests a singular noun which matches the answer.
'in one complex protecting underground chamber' is the wordplay.
'complex' indicates an anagram.
'protecting' means one lot of letters goes inside another.
'underground chamber' becomes 'crypt' (I've seen this before).
'in'+'one'='inone'
'inone' with letters rearranged gives 'enion'.
'enion' going around 'crypt' is 'ENCRYPTION'.
Can you help me to learn more?
