Stop fool flying -- it's not worth much apparently
I believe the answer is:
groundnut
'stop fool flying' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'it's not worth much apparently' is the wordplay.
I cannot quite understand how this works, but
'not' could be 'un' (I've seen this in other clues) and 'un' is present in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for groundnut that I've seen before include "something to eat" , "Peanut" , "food" , "edible tuber?" , "Nibble" .)
