Dialect brings stress (6)
I believe the answer is:
accent
I believe this clue is a double definition.
'dialect' is the first definition.
('accent' can be a synonym of 'dialect')
'stress' is the second definition.
('accent' can be a synonym of 'stress')
'brings' acts as a link.
(Other definitions for accent that I've seen before include "Stress - regional dialect" , "Emphasise" , "Regional speech characteristic" , "A localised way of speaking" , "Pronunciation in a locality" .)
