To a point, it has a certain amount of taste (4)
I believe the answer is:
stew
'taste' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'to a point it has a certain amount' is the wordplay.
'to a point' becomes 'S' (S is an example).
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'has' says to put letters next to each other.
'a certain amount' becomes 'ew' (I can't explain this - if you can you should believe this answer much more).
's'+'t'+'ew'='STEW'
'of' is the link.
Can you help me to learn more?
(Other definitions for stew that I've seen before include "Agitation caused by worry" , "Fret" , "Meat and veg dish" , "Braise" , "Go West for this dish" .)
