Religious group cut record? Yes, in a state where nothing is leaked! (7)
I believe the answer is:
secrecy
'a state where nothing is leaked' is the definition.
I can't tell whether this defines the answer.
'religious group cut record? yes' is the wordplay.
'religious group' becomes 'sect' (eg a religious sect).
'cut' means to remove the last letter.
'record?' becomes 'rec' (short for record).
'yes' becomes 'y'.
'sect' with its final letter taken off is 'sec'.
'sec'+'rec'+'y'='SECRECY'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for secrecy that I've seen before include "openly, without protection of this" , "Suppression of information" , "Confidentiality" , "Stealth; covertness" , "Covert activity" .)
