Spinach with a little anchovy? It's legendary (4)
I believe the answer is:
saga
'it's legendary' is the definition.
I can't tell whether this defines the answer.
'spinach with a little anchovy?' is the wordplay.
'spinach' becomes 'sag' (variant of saag, term in Indian cooking).
'with' means one lot of letters go next to another.
'a little' indicates taking the first letters.
The initial letter of 'anchovy' is 'a'.
'sag'+'a'='SAGA'
Can you help me to learn more?
(Other definitions for saga that I've seen before include "Long narrative" , "Epic story" , "Long detailed story" , "A long story or poem - it's a gas" , "Chronicle; adventure" .)
