Icon with baby disturbed attendant at sea (5,3)
I believe the answer is:
cabin boy
'attendant at sea' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'icon with baby disturbed' is the wordplay.
'with' is a charade indicator (letters next to each other).
'disturbed' is an anagram indicator (the order of letters is disturbed).
'icon'+'baby'='iconbaby'
'iconbaby' anagrammed gives 'CABIN BOY'.
Can you help me to learn more?
(Other definitions for cabin boy that I've seen before include "youngster on ship" , "Ship's attendant" , "Young waiter on ship" , "Servant aboard ship" , "youth on board" .)
