Cheers with a bit of speculation - figure buffoon's heading for exit? (2,4)
I believe the answer is:
so long
'exit?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for so long that I've seen before include "Ta-Ta!" , "Informal goodbye; see you" , "Informal goodbye - protracted?" , "Goodbye (colloq.)" , "Cheerio, bye-bye" .)
