Food grower focussed on the one that doesn't turn up (2-4)
I believe the answer is:
no-show
'grower focussed on the one that doesn't turn up' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'food' is the wordplay.
I cannot quite see how this works, but
'food' could be 'nosh' (nosh is a kind of food) and 'nosh' is found within the answer.
The remaining letters 'ow' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for no-show that I've seen before include "Non-attender" , "Someone who neither keeps nor cancels an engagement" , "Failure to appear" , "One failing to appear as booked" , "Person who fails to cancel -- who's on (anag)" .)
