It's nourishing to consume around mid-October (4)
I believe the answer is:
soup
'mid-october' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'it's nourishing to consume around' is the wordplay.
'it's nourishing' becomes 'oup' (I am not sure about this - if you are sure you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'around' says to take the centre.
The centre of 'consume' is 's'.
'oup' after 's' is 'SOUP'.
Can you help me to learn more?
(Other definitions for soup that I've seen before include "Eg, minestrone" , "Mulligatawny or borscht?" , "Preliminary course" , "Eskimo people" , "Bisque, for example" .)
