Exaggerate accent (6)
I believe the answer is:
stress
I believe this clue is a double definition.
'exaggerate' is the first definition.
'accent' is the second definition.
(synonyms)
(Other definitions for stress that I've seen before include "suffering" , "Put weight on" , "Feeling of pressure" , "why off work?" , "Emphasis: result often of being under pressure" .)
