Valuable bit of rock near port and point found in Long Island - somewhere sailors should avoid (7)
I believe the answer is:
lorelei
'valuable bit of rock' is the definition.
I know that 'rock' relates to this answer. I also know that both the answer and definition are singular nouns
'near port and point found in long island somewhere sailors should avoid' is the wordplay.
I cannot really understand how this works, but
'port' could be 'l' (abbreviation for L - 'port' is 'left' on a boat) and 'l' is found within the answer.
'point' could be 'e' (compass point) and 'e' is located in the answer.
'long' could be 'l' and 'l' is present in the answer.
'island' could be 'i' (geographical abbreviation) and 'i' is present in the answer.
The remaining letters 'ore' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lorelei that I've seen before include "Rock-dwelling siren" , "Siren of German legend who lured boatmen in the Rhine to destruction" , "Attractive woman" , "Legendary siren who lured Rhine boatmen to destruction" , "High rock in the Rhine gorge" .)
