Tension or anguish after DI is dismissed (6)
I believe the answer is:
stress
'tension' is the definition.
(I know that tension can be written as stress)
'anguish after di is dismissed' is the wordplay.
I cannot really see how this works, but
'dismissed' could be 'st' and 'st' is found within the answer.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for stress that I've seen before include "Dwell on" , "possible excuse for sickie?" , "Highlight" , "why off work?" , "Emphasise the pressure" .)
