It's not possible to have a party without toilet facilities? (2,3,2)
I believe the answer is:
no can do
'it's not possible' is the definition.
(I've seen this in another clue)
'a party without toilet facilities?' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is found in the answer.
'party' could be 'do' (do is a kind of party) and 'do' is found in the answer.
'without' could be 'no' and 'no' is found in the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to have' is the link.
Can you help me to learn more?
(Other definitions for no can do that I've seen before include "off-putting response" , "Absolutely not!" , "Impossible, I'm afraid!" , "Unable to help" , "Nothing manageable" .)
