Make a big fuss - and continue to do so (5,2)
I believe the answer is:
carry on
'do so' is the definition.
'carry on' can be an answer for 'do' (thesaurus). I'm not sure about the 'so' bit.
'make a big fuss and continue' is the wordplay.
I cannot quite see how this works, but
'make' could be 'carry' (carrying is a kind of making) and 'carry' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for carry on that I've seen before include "Improper behaviour" , "Display of fussing" , "Questionable behaviour" , "play around" , "Flirt" .)
