Purpose of home with temporary accommodation (6)
I believe the answer is:
intent
'purpose' is the definition.
(I know that purpose can be written as intent)
'home with temporary accommodation' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'with' says to put letters next to each other.
'temporary accommodation' becomes 'tent' (people stay in a tent temporarily).
'in'+'tent'='INTENT'
'of' acts as a link.
(Other definitions for intent that I've seen before include "Purpose under canvas" , "7 Purpose; fixed (upon)" , "Committed" , "With attention concentrated, bent on" , "Objective" .)
