Finish, annually, welcoming a time at home (6)
I believe the answer is:
patina
'finish' is the definition.
(thesaurus)
'annually welcoming a time at home' is the wordplay.
'annually' becomes 'pa' ('p.a.' can be a synonym of 'annually').
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'time' becomes 't'.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'a'+'t'+'in'='atin'
'pa' enclosing 'atin' is 'PATINA'.
(Other definitions for patina that I've seen before include "Developing surface film; sheen" , "Film on copper or bronze" , "Surface shine" , "Film forming on bronze" , "Green coating on bronze" .)
