Tuck into this lunch, finally, after noon (4)
I believe the answer is:
nosh
'tuck into this lunch finally after noon' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'into this lunch finally after noon' is the wordplay.
'finally' says to take the final letters.
'after' is a charade indicator (letters next to each other).
'noon' becomes 'n' (abbreviation).
The last letters of 'into this lunch' are 'osh'.
'osh' put after 'n' is 'NOSH'.
Can you help me to learn more?
(Other definitions for nosh that I've seen before include "eating this?" , "Slangy food or meal" , "Scoff" , "Food (Yiddish)" , "Eat (sl.)" .)
