Produce tinkle to interrupt fight (5,3)
I believe the answer is:
bring out
'produce' is the definition.
(I know that produce can be written as bring out)
'tinkle to interrupt fight' is the wordplay.
'tinkle' becomes 'ring'.
'to interrupt' indicates putting letters inside.
'fight' becomes 'bout' (as in a bout in boxing).
'ring' inserted within 'bout' is 'BRING OUT'.
(Other definitions for bring out that I've seen before include "Issue" , "Publish" , "Elicit" , "Emphasise" , "Emphasize (a feature)" .)
