Second home providing returns in the end (5)
I believe the answer is:
finis
'the end' is the definition.
(I've seen this before)
'second home providing returns' is the wordplay.
'second' becomes 's' (common abbreviation).
'home' becomes 'in' ('he's home' can mean 'he's in').
'providing' becomes 'if' (I've seen this in other clues).
'returns' says the letters should be written backwards.
's'+'in'+'if'='sinif'
'sinif' written backwards gives 'FINIS'.
'in' is the link.
(Other definitions for finis that I've seen before include "conclusion!" , "End (of book or film)" .)
