Stress that may be acute? (6)

I believe the answer is:

accent

I believe this clue is a double definition.

'stress' is the first definition.
(accent can mean to emphasise or stress)

'acute?' is the second definition.
(acute is a kind of accent)

'that may be' acts as a link.

(Other definitions for accent that I've seen before include "Regional speech characteristic" , "Grave, perhaps" , "Tone of voice" , "intensity" , "Pronunciation in a locality" .)

I've seen this clue in The Times and The Sun.
