Disobedient aboard sinking boat, men worried about commotion (13)
I believe the answer is:
insubordinate
'disobedient' is the definition.
(similar in meaning)
'aboard sinking boat men worried about commotion' is the wordplay.
I cannot really understand how this works, but
'aboard' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
'boat' could be 'sub' (I've seen this before) and 'sub' is found in the answer.
'men' could be 'or' (military abbreviation for Other Ranks) and 'or' is present in the answer.
'worried' could be 'ate' (something worrying may eat someone up) and 'ate' is found within the answer.
'commotion' could be 'din' (synonyms) and 'din' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for insubordinate that I've seen before include "Not submissive to authority" , "Defiant of authority" , "Insolent" , "Rebellious" , "Mutinous" .)
