Complaint from crew, eating nothing (4)
I believe the answer is:
moan
'complaint' is the definition.
(thesaurus)
'crew eating nothing' is the wordplay.
'crew' becomes 'man' (I've seen this before).
'eating' means one lot of letters goes inside another.
'nothing' becomes 'o' (looks like zero - 0).
'man' placed around 'o' is 'MOAN'.
'from' is the link.
(Other definitions for moan that I've seen before include "Complain, groan" , "Express pain" , "Complain; mournful sound" , "Lament; grumble" , "Complain, grumble" .)
