Home closed twice, completely (2,4)
I believe the answer is:
in toto
'completely' is the definition.
(I've seen this in another clue)
'home closed twice' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'closed' becomes 'to' (as in a door closed to).
'twice' says to double the letters.
'to' doubled is 'toto'.
'in'+'toto'='IN TOTO'
(Other definitions for in toto that I've seen before include "Tranquillity" , "Altogether, completely" , "In entirety" , "As a whole (Latin)" , "Wholly" .)
