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' means one lot of letters goes inside another.
'a bit of' suggests taking the first letters.
'a drink' becomes 'kae' (I can't justify this - if you can you should believe this answer much more).
The first letter of 'luck' is 'l'.
'l' going into 'kae' is 'KALE'.
'and' is the 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" .)
