Negative characters to form company? I don’t find it possible (2,3,2)
I believe the answer is:
no can do
'i don't find it possible' is the definition.
(phrase used to say you think something impossible)
'negative characters to form company?' is the wordplay.
'negative' becomes 'no' (no is a kind of negative).
'characters to form company?' becomes 'CandO' (letters for the abbreviation co).
'no'+'cando'='NO CAN DO'
(Other definitions for no can do that I've seen before include "Bring-a-bottle party?" , "Unable to help" , "Impossible, I'm afraid!" , "Informal expression of refusal" , "Can't manage it, see doc anon" .)
