Fixing temporary accommodation (7)
I believe the answer is:
lodging
This clue is a double definition.
'fixing' is the first definition.
(lodging is a kind of fixing)
'temporary accommodation' is the second definition.
(I've seen this before)
(Other definitions for lodging that I've seen before include "Living in digs" , "Putting on deposit" , "Depositing" , "Temporary accommodation" , "For security, giving up" .)
