Mediterranean form of trance (6)
I believe the answer is:
cretan
'mediterranean form' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of trance' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'trance' anagrammed gives 'CRETAN'.
Can you help me to learn more?
(Other definitions for cretan that I've seen before include "Native of Minoan island" , "Island nationality of citizen of Heraklion" , "One from Greece's largest island" , "Native of a large Greek island" , "One from largest Greek isle" .)
