How to make a round table in the cheapest manner? (3,7)
I believe the answer is:
cut corners
'a round table in the cheapest manner?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'how to make' is the wordplay.
'how' becomes 'corners' (I can't explain this - if you can you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'make' becomes 'cut' (cutting is a kind of making).
'corners' after 'cut' is 'CUT CORNERS'.
Can you help me to learn more?
(Other definitions for cut corners that I've seen before include "Skimp on effort" , "Miss out things to save money" .)
