Head of the sailors instanced nightly by Arabian damsel (6)
I believe the answer is:
sinbad
'head of the sailors instanced nightly by arabian damsel' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'head of the sailors instanced nightly by arabian damsel' is the wordplay.
'head of' says to take the initial letters.
The first letters of 'sailors instanced nightly by arabian damsel' is 'SINBAD'.
Can you help me to learn more?
(Other definitions for sinbad that I've seen before include "Sailor of Eastern tale" , "Adventurous sailor of Arabian Nights or pantomime" , "Legendary mariner noted for seven voyages" , "Legendary sailor from Arabian nights" , "Pantomime sailor from the Arabian Nights (6)" .)
