Cloaked in secrecy, clerics convert to another form (7)
I believe the answer is:
recycle
'another form' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'cloaked in secrecy clerics convert' is the wordplay.
'cloaked in' says the answer is hidden in the clue (cloak can mean to conceal).
'RECYCLE' is hidden in the letters of 'secrecy clerics convert'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for recycle that I've seen before include "Keep and use again" , "To use up left-overs" , "Convert waste to new usage" , "Use (rubbish) again" , "Make new use of" .)
