Margaret right to back Low in seat of judgment (9)
I believe the answer is:
courtroom
'seat of judgment' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'margaret right to back low' is the wordplay.
'margaret' becomes 'court' (I am not sure about this - if you are sure you should believe this answer much more).
'right' becomes 'r' (common abbreviation).
'to back' is a reversal indicator.
'low' becomes 'moo' (both can mean to make a cow noise).
'moo' in reverse letter order is 'oom'.
'court'+'r'+'oom'='COURTROOM'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for courtroom that I've seen before include "trial venue" , "trying situation" .)
