Courage of unknown vicar shown up after booby trap (7)
I believe the answer is:
bravery
'courage' is the definition.
(I know that courage can be written as bravery)
'unknown vicar shown up after booby trap' is the wordplay.
'unknown' becomes 'y' (algebra).
'vicar' becomes 'rev' (reverend).
'shown up' says the letters should be written in reverse (in a down clue, letters go up).
'after' means one lot of letters go next to another.
'booby trap' becomes 'bra' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'y'+'rev'='yrev'
'yrev' reversed gives 'very'.
'very' after 'bra' is 'BRAVERY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for bravery that I've seen before include "Courageous quality" , "Valour" , "Courage" , "Heroism" , "daring" .)
