Panellist on trial (5)
I believe the answer is:
juror
This clue might be a double definition.
'panellist' is the first definition.
(I know that juror is a type of panellist)
'trial' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for juror that I've seen before include "Court panellist" , "Trial panellist" , "person to deliver verdict" , "One in box in court" , "One of those responsible for verdict" .)
