Root vegetable, one of a group found among cabbages? (5)
I believe the answer is:
swede
'root vegetable' is the definition.
(swede is a kind of root vegetable)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for swede that I've seen before include "Foreigner" , "plant" , "Citizen of kingdom" , "Cattle fodder" , "Nobel for one" .)
