Barely manage to get fix (6)
I believe the answer is:
scrape
This could be a double definition.
'barely manage' is the first definition.
'scrape' can be an answer for 'manage' (thesaurus). I'm not sure about the 'barely' bit.
'fix' is the second definition.
(both can mean a dangerous situation)
'to get' is the link.
Can you help me to learn more?
(Other definitions for scrape that I've seen before include "Move gratingly over" , "Difficult situation; graze" , "Scratch; just make (living)" , "Grate, scratch" , "pickle!" .)
