Alias Marian (6)
I believe the answer is:
marina
'alias' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'marian' is the wordplay.
'marian' can be anagrammed to 'MARINA'.
However, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for marina that I've seen before include "boating facility" , "Pleasure-boat dock" , "Yacht harbour" , "Base for pleasure boats" , "seaside area" .)
