A meal's been cooked for sailors (4,6)
I believe the answer is:
able seamen
'sailors' is the definition.
(able seaman is a kind of sailor)
'a meal's been cooked' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'meals'+'been'='mealsbeen'
'mealsbeen' is an anagram of 'bleseamen'.
'a'+'bleseamen'='ABLE SEAMEN'
'for' is the link.
(Other definitions for able seamen that I've seen before include "sailors" , "ratings" .)
