Neat act with cue going wrong producing stress (10)
I believe the answer is:
accentuate
'stress' is the definition.
(I've seen this before)
'neat act with cue going wrong' is the wordplay.
'with' means one lot of letters go next to another.
'going wrong' is an anagram indicator.
'neat'+'act'+'cue'='neatactcue'
'neatactcue' is an anagram of 'ACCENTUATE'.
'producing' is the link.
(Other definitions for accentuate that I've seen before include "Stress" , "Make more prominent" , "Emphasise" , "Draw attention to" .)
