Temporary home — call to accommodate one (7)
I believe the answer is:
interim
'temporary' is the definition.
(similar in meaning)
'home call to accommodate one' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'call' becomes 'term' (to term something is to call it something).
'to accommodate' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'term' enclosing 'i' is 'terim'.
'in'+'terim'='INTERIM'
(Other definitions for interim that I've seen before include "Temporary - provisional" , "Meantime; temporary" , "Meantime - provisional" , "Meanwhile" , ", I'm put in grave situation initially" .)
