Saint George dismissed Georgian clique (3)
I believe the answer is:
set
'dismissed georgian clique' is the definition.
'set' can be an answer for 'clique' (thesaurus). I'm not sure about the 'dismissed georgian' bit.
'saint george' is the wordplay.
'saint' becomes 's'.
'george' becomes 'et' (I can't explain this - if you can you should believe this answer much more).
's'+'et'='SET'
Can you help me to learn more?
(Other definitions for set that I've seen before include "Major unit of tennis match" , "Solidify like jelly" , "Put, coagulate" , "Solidified" , "Group; hard" .)
