Free French article about toilets (7)
I believe the answer is:
unloose
'free' is the definition.
(I know that free can be written as unloose)
'french article about toilets' is the wordplay.
'french article' becomes 'une' (indefinite article in French).
'about' indicates putting letters inside.
'toilets' becomes 'loos' (loo can informally mean a toilet).
'une' placed around 'loos' is 'UNLOOSE'.
(Other definitions for unloose that I've seen before include "Let free" , "Set free" , "Release" .)
