I'm a little stuck... Click here to teach me more about this clue!

'cloak that conceals' is the definition.
'capote' can be an answer for 'cloak' (capote is a kind of cloak). I'm not sure about the rest of the definition.

'a drug in church' is the wordplay.
'drug' becomes 'pot' (slang term for cannabis).
'in' is an insertion indicator.
'church' becomes 'CE' (abbreviation for Church of England).
'a'+'pot'='apot'
'apot' going inside 'ce' is 'CAPOTE'.

Can you help me to learn more?
