In church smeller misses nothing - this included? (7)
I believe the answer is:
incense
'nothing this included?' is the definition.
The definition suggests a singular noun which matches the answer.
'in church smeller misses' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'smeller misses' becomes 'nse' (I can't explain this - if you can you should give a lot more credence to this answer).
'in'+'ce'+'nse'='INCENSE'
Can you help me to learn more?
(Other definitions for incense that I've seen before include "Substance burnt in church" , "Rouse to anger" , "To outrage" , "Anger - holy smoke!" , "source of smoke" .)
