Avoid nothing (4)
I believe the answer is:
duck
I believe this is a double definition.
'avoid' is the first definition.
(ducking is a kind of avoiding)
'nothing' is the second definition.
(thesaurus)
(Other definitions for duck that I've seen before include "eg Jemima, Donald" , "Evade, nought (cricket)" , "strong cloth" , "Love" , "nothing" .)
