Murderous brother confines bishop in hut (5)
I believe the answer is:
cabin
'hut' is the definition.
(I've seen this before)
'murderous brother confines bishop' is the wordplay.
'murderous brother' becomes 'cain' (I have seen 'Brother of Abel ' mean 'cain' so perhaps 'brother' could also mean 'cain'. I am not sure about the 'murderous' bit.).
'confines' is an insertion indicator.
'bishop' becomes 'b' (abbreviation used in chess).
'cain' going around 'b' is 'CABIN'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cabin that I've seen before include "Small wooden shelter" , "Marine digs" , "modest accommodation" , "Building" , "Wooden dwelling" .)
