Determine the outcome of sectarian troubles (9)
I believe the answer is:
ascertain
'determine the outcome' is the definition.
'ascertain' can be an answer for 'determine' (synonyms). I am not sure about the 'the outcome' bit.
'sectarian troubles' is the wordplay.
'troubles' indicates an anagram (I've seen 'troubled' mean this).
'sectarian' is an anagram of 'ASCERTAIN'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ascertain that I've seen before include "Verify" , "Find out by making enquiries in sectarian way" , "settle" , "Find out - make sure" , "Establish (the facts)" .)
