Miss the target? Definitely no! (3,2,1,4,4)
I believe the answer is:
not by a long shot
'definitely no' is the definition.
Both the definition and answer are adverbs. Maybe you can see a link between them that I can't see?
'miss the target?' is the wordplay.
I cannot quite understand how this works, but
'miss' could be 'long' (longing is a kind of missing) and 'long' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for not by a long shot that I've seen before include "By no means" , "how a tap-in is scored?" .)
