Shelter top of kale and different vegetable (4)
I believe the answer is:
leek
'different vegetable' is the definition.
'leek' can be an answer for 'vegetable' (I've seen this in another clue). I'm unsure of the 'different' bit.
'shelter top of kale' is the wordplay.
'shelter' becomes 'lee' (as in lee side, the side sheltered from wind).
'top of' says to take the initial letters.
The initial letter of 'kale' is 'k'.
'lee'+'k'='LEEK'
'and' is the link.
Can you help me to learn more?
(Other definitions for leek that I've seen before include "Vegetable - Welsh symbol" , "Staffordshire town?" , "Plant; Welsh emblem" , "Vegetable associated with Wales" , "Vegetable of the onion family" .)
