The imaginable part may be Continental (7)
I believe the answer is:
belgian
'continental' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'the imaginable part may be' is the wordplay.
I cannot really see how this works, but
'be' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for belgian that I've seen before include "Hercule Poirot's nationality" , "Eg, Brussels native" , "One from Liege, say" , "Bengali from a European state?" , "Nationality of Rene Magritte" .)
