Fringe documentary oddly cut and edited (5)
I believe the answer is:
outer
'fringe' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for outer that I've seen before include "External kind of route" , "Ring for double scores on a dartboard" , "Ring furthest from the bullseye" , "External; peripheral" , "This space is beyond earth's atmosphere" .)
