I had the French loaf (4)
I believe the answer is:
idle
'loaf' is the definition.
(thesaurus)
'i had the french' is the wordplay.
'i had' becomes 'id' (I'd).
'the french' becomes 'le'.
'id'+'le'='IDLE'
(Other definitions for idle that I've seen before include "Not occupied" , "Unoccupied or not in use" , "Futile" , "Disliking work" , "no longer employed?" .)
