Tom sailed off, leaving maiden marooned (8)
I believe the answer is:
isolated
'marooned' is the definition.
(I know that marooned can be written as isolated)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for isolated that I've seen before include "Set apart, quarantined" , "Cut off, remote" , "kept separate" , "Alone, set apart" , "hard to find" .)
