AllI need is this clue to complete can anyone help
15a 12 providing little sustenance (6)
(answer to 12 is "love story")
W-E-I- All that comes to mind is wienie or weenie for frankfurter sausage but I cant reconcile this with the clue. Understood that weenie is small and frankfurter is sustenance but where does "12" fit into all that?
Can anyone help?
