Lies endlessly about soft food (4,3)
I believe the answer is:
pork pie
'food' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'lies endlessly about soft' is the wordplay.
'lies' becomes 'porkies' (rhyming slang - porky pies).
'endlessly' means to remove the last letter.
'about' is an insertion indicator.
'soft' becomes 'p' (musical abbreviation for 'piano').
'porkies' with its last letter removed is 'porkie'.
'porkie' placed around 'p' is 'PORK-PIE'.
Can you help me to learn more?
(Other definitions for pork pie that I've seen before include "Food item" , "That isn't true" , "Fib - meaty snack - hat" , "going over one's head?" , "One going to the head" .)
