Resident properly involved in bloody uprising (7)
I believe the answer is:
dweller
'resident' is the definition.
(I know that resident can be written as dweller)
'properly involved in bloody uprising' is the wordplay.
'properly involved' becomes 'well' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'bloody' becomes 'red'.
'uprising' shows that the letters should be reversed in order.
'red' back-to-front is 'der'.
'well' inserted into 'der' is 'DWELLER'.
Can you help me to learn more?
(Other definitions for dweller that I've seen before include "Denizen" , "Resident" , "One living (at a place)" , "liver" , "One residing (in a place)" .)
