Free toilets close to home (5)
I believe the answer is:
loose
'free' is the definition.
('loose' can be similar in meaning to 'free')
'toilets close to home' is the wordplay.
'toilets' becomes 'loos' (loo is a kind of toilet).
'close to' indicates one should take the final letters (the close/ending of).
The last letter of 'home' is 'e'.
'loos'+'e'='LOOSE'
(Other definitions for loose that I've seen before include "Unsecured; dissolute" , "Untie(d)" , "Not fixed; inexact" , "released from confinement" , "Not bound" .)
