Subjects of inquiry involving university political movements (6)
I believe the answer is:
causes
'political movements' is the definition.
(I've seen this in another clue)
'subjects of inquiry involving university' is the wordplay.
I cannot really understand how this works, but
'university' could be 'u' (abbreviation for university) and 'u' is located in the answer.
'subjects' could be 'cases' (case is a kind of subject) and 'cases' is found in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for causes that I've seen before include "They give rise to effects" , "Brings" , "'Reasons, grounds (6)'" , "Origins or crusaders" , "They produce effects" .)
