Final score left United going over amongst support (6)
I believe the answer is:
result
'final score' is the definition.
(I've seen this before)
'left united going over amongst support' is the wordplay.
'left united' becomes 'lu' (this might be a standard abbreviation of which I'm unaware).
'going over' says the letters should be written in reverse.
'amongst' is an insertion indicator (I've seen this in other clues).
'support' becomes 'rest' (e.g. a shoulder rest is a support for shoulder).
'lu' back-to-front is 'ul'.
'ul' placed within 'rest' is 'RESULT'.
Can you help me to learn more?
(Other definitions for result that I've seen before include "Final score" , "Rustle (anag.)" , "Outcome of an undertaking" , "End - issue" , "Final outcome" .)
