Four managed outside and survived (5)
I believe the answer is:
lived
'survived' is the definition.
('live' can be a synonym of 'survive')
'four managed outside' is the wordplay.
'four' becomes 'iv' ('IV' can be a synonym of 'four').
'managed' becomes 'led'.
'outside' indicates putting letters inside.
'iv' going within 'led' is 'LIVED'.
'and' is the link.
(Other definitions for lived that I've seen before include "Escaped destruction" , "Existed or dwelt" .)
