Put up with quartet? Last chance to scold and revile! (10)
I believe the answer is:
vituperate
'revile' is the definition.
(I know that revile can be written as vituperate)
'put up with quartet? last chance to scold' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'with' says to put letters next to each other.
'quartet?' becomes 'vi' (I can't justify this - if you can you should believe this answer much more).
'last' suggests the final letters.
'to scold' becomes 'rate' (I've seen this in other clues).
The final letter of 'chance' is 'e'.
'put' backwards is 'tup'.
'tup' after 'vi' is 'vitup'.
'vitup'+'e'+'rate'='VITUPERATE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for vituperate that I've seen before include "Blame violently - I've a putter (anag)" , "Revile" , "Abuse" , "curse" , "blackguard" .)
