Free toilets by end of lane (5)
I believe the answer is:
loose
'free' is the definition.
(similar in meaning)
'toilets by end of lane' is the wordplay.
'toilets' becomes 'loos' (loo is a kind of toilet).
'by' is a charade indicator (letters next to each other).
'end of' indicates one should take the final letters.
The last letter of 'lane' is 'e'.
'loos'+'e'='LOOSE'
(Other definitions for loose that I've seen before include "Slack or immoral" , "Not strict" , "Not fitting tightly" , "Unfettered" , "Freed" .)
