Get fantastic taco from market stand in the south and hang the expense (2,3,5)
I believe the answer is:
at all costs
'get fantastic taco from market stand in' is the definition.
I can't tell whether this defines the answer.
'south and hang the expense' is the wordplay.
'south' becomes 'S' (abbreviation).
'and' means one lot of letters go next to another.
'hang' becomes 'atall' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'the expense' becomes 'cost' (cost is a kind of expense).
'atall'+'cost'='atallcost'
's' put after 'atallcost' is 'AT ALL COSTS'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for at all costs that I've seen before include "Regardless of what needs to be paid" , "Regardless of the sacrifice involved" , "Regardless of expense" , "Regardless of the price" , "whatever may happen" .)
