Feel acute embarrassment, His Excellency has court order first (6)
I believe the answer is:
writhe
'feel acute embarrassment' is the definition.
(I've seen this before)
'his excellency has court order first' is the wordplay.
I cannot quite see how this works, but
'excellency' could be 'he' and 'he' is located in the answer.
'order' could be 'writ' (I've seen this before) and 'writ' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for writhe that I've seen before include "Twist in agony" , "Squirm in pain" , "Twist as in pain" , "feel acute embarrassment" , "It's painful moving" .)
