Ancient area of Casablanca, say, seemed inaccessible to some extent (6)
I believe the answer is:
medina
'ancient area of casablanca' is the definition.
I can't judge whether this definition defines the answer.
'say seemed inaccessible to some extent' is the wordplay.
'to some extent' says the answer is hidden in the clue.
'MEDINA' is hidden within 'say seemed inaccessible'.
Can you help me to learn more?
(Other definitions for medina that I've seen before include "Native quarter in North African cities" , "Middle Eastern city" , "Holy city in Saudi Arabia for maiden" , "Mohammed burial city" , "Location of the tomb of Mohammed" .)
