seafarer

I'm a little stuck... Click here to teach me more about this clue!

'salt' is the definition.
(synonyms)

'fears are rightly misconstrued' is the wordplay.
'fears are' can be anagrammed to 'SEAFARER'.
But, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for seafarer that I've seen before include "One going by ship" , "One on the water" , "Traveller over water" , "Jack" , "Salt" .)

I've seen this clue in The Telegraph.
