Like that measure in trial by jury in Scotland? (6)
I believe the answer is:
assize
'jury in scotland?' is the definition.
'assize' can be an answer for 'jury' (I have seen 'Scottish jury' mean 'assize' so perhaps 'jury' could also mean 'assize'). I'm not sure about the 'in scotland?' bit.
'like that measure in trial by' is the wordplay.
'like' becomes 'as'.
'that measure in trial' becomes 'size' (I am not sure about this - if you are sure you should believe this answer much more).
'by' means one lot of letters go next to another.
'as'+'size'='ASSIZE'
Can you help me to learn more?
(Other definitions for assize that I've seen before include "Old English court" , "Jury (Scotland)" , "sitting in judgment" , "Historical court" , "Scottish jury" .)
