Distressing pressure? (6)
I believe the answer is:
stress
'pressure?' is the definition.
(I've seen this before)
'distressing' is the wordplay.
'STRESS' is hidden within the letters.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for stress that I've seen before include "Lay emphasis on - it's a strain" , "'Strain, tension (6)'" , "Strain or accentuate" , "Emphasize" , "Tension - accent" .)
