Mend about two (6)
I believe the answer is:
repair
'mend' is the definition.
(I know that mend can be written as repair)
'about two' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'two' becomes 'pair' (pair is a kind of two).
're'+'pair'='REPAIR'
(Other definitions for repair that I've seen before include "retire" , "Travel or proceed toward some place" , "Patch up" , "remedy" , "Restore to good order" .)
