With a bit of luck, a drink and something to eat (4)
I believe the answer is:
kale
'something to eat' is the definition.
(kale is a kind of food)
'with a bit of luck a drink' is the wordplay.
'with' indicates putting letters inside.
'a bit of' says to take the initial letters.
'a drink' becomes 'kae' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'luck' is 'l'.
'l' inserted inside 'kae' is 'KALE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for kale that I've seen before include "Hardy cabbage" , "Curly-leafed cabbage" , "Cabbage in a lake" , "Vegetable" , "Crinkled-leaf cabbage" .)
