In no way immediately! (3)
I believe the answer is:
now
'immediately' is the definition.
(I've seen this before)
'in no way' is the wordplay.
I cannot really understand how this works, but
'no' could be 'o' (O resembles 0) and 'o' is found in the answer.
'way' could be 'w' (Compass direction - West) and 'w' is found in the answer.
A single letter 'n' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for now that I've seen before include "The present moment" , "At this moment in time" , "At the present time" , "Today" , "Immediately" .)
