Stressed given coaching in voice (4)
I believe the answer is:
taut
'stressed' is the definition.
(I've seen this in other clues)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for taut that I've seen before include "Without slack" , "Stretched tight or disciplined" , "Fully stretched" , "Pulled or drawn tight" , "On the slope" .)
