Misguidedly remain in the briny! (6)
I believe the answer is:
marine
'briny' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'misguidedly remain' is the wordplay.
'misguidedly' indicates anagramming the letters.
'remain' is an anagram of 'MARINE'.
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for marine that I've seen before include "seaman" , "Soldier-sailor" , "jolly" , "Soldier associated with a navy" , "'Nautical, maritime (6)'" .)
