Conclusion yet to be reached in a riddle - yeh, right! (2,2)
I believe the answer is:
as if
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for as if that I've seen before include "Or though" , "a voice of doubt" , "Seemingly" , "I very much doubt it!" , "highly unlikely" .)
