Get by, manage (4)
I believe the answer is:
cope
I believe this is a double definition.
'get by' is the first definition.
(synonyms)
'manage' is the second definition.
(manage can mean to cope or do well)
(Other definitions for cope that I've seen before include "Manage, make do" , "Priest's ceremonial cloak" , "Manage, come to terms with" , "Manage effectively" , "Deal effectively (with a difficulty)" .)
