After judge catches Republican lying (9)
I believe the answer is:
prostrate
'lying' is the definition.
(I've seen this before)
'after judge catches republican' is the wordplay.
I cannot really understand how this works, but
'judge' could be 'rate' (rating is a kind of judging) and 'rate' is found in the answer.
'republican' could be 'r' (abbreviation in US politics) and 'r' is present in the answer.
'after' could be 'post' (prefix meaning after, eg post-war) and 'post' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for prostrate that I've seen before include "helpless" , "Flat" , "Face to the ground" , "Lying face downwards" , "Horizontal" .)
