Part of life men definitely make better (5)

I believe the answer is:

emend

'make better' is the definition.
(emending is a kind of making better)

'part of life men definitely' is the wordplay.
'part of' indicates a hidden word.
'EMEND' is hidden within 'life men definitely'.

(Other definitions for emend that I've seen before include "Make changes to (a text)" , "get rid of faults" , "do editorial work" , "Remove errors" , "make an improvement" .)

I've seen this clue in The Independent.
