Manage, get by (4)
I believe the answer is:
cope
I believe this is a double definition.
'manage' is the first definition.
(manage can mean to cope or do well)
'get by' is the second definition.
(synonyms)
(Other definitions for cope that I've seen before include "special cloak" , "Join" , "Rise to the occasion" , "Manage, come to terms with" , "Firmly based (in)" .)
