Highly unlikely meal opportunity for Mrs Sprat? (3,6)
I believe the answer is:
fat chance
'highly unlikely meal' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'opportunity for mrs sprat?' is the wordplay.
'opportunity' becomes 'chance' (synonyms).
'for' says to put letters next to each other (I've seen this in other clues).
'mrs sprat?' becomes 'fat' (I can't justify this - if you can you should believe this answer much more).
'chance' put after 'fat' is 'FAT CHANCE'.
Can you help me to learn more?
(Other definitions for fat chance that I've seen before include "Slim hope, paradoxically!" , "Slender hope (odd though that sounds)" , "Little prospect" , "that won't happen" , "It will never happen!" .)
