Islander in trance given shake (6)
I believe the answer is:
cretan
'islander' is the definition.
(someone from Crete)
'trance given shake' is the wordplay.
'trance' can be anagrammed to 'CRETAN'.
However, I'm unsure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cretan that I've seen before include "Inhabitant of a large Greek island" , "Native of Greek island south of mainland (6)" , "Island nationality of citizen of Heraklion" , "One from Greece's largest island" , "Native of a large Greek island" .)
