Thus might problem-solver make four (3,3,3,3,8)
I believe the answer is:
put two and two together
'thus might problem-solver' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'make four' is the wordplay.
I cannot really see how this works, but
'make' could be 'get' (getting is a kind of making) and 'get' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for put two and two together that I've seen before include "getting formula to make a quartet" , "compose a quartet" , "Reach obvious conclusion" , "Draw an obvious conclusion" , "what transpired" .)
