Johnny11  +  302758 Mon, 11 Dec 06 10:12 AM I have got the following sentence: Diabetes: Are There New Treatments Available? Is it grammaticali correct? Or would it be accurate to use: Diabetes – Are There New Treatments Available? or Diabetes - Are There New Treatments Available? I am a little confused over the use of the hyphen and the em dash in english language. I would appreciate any help. Thank you in advance.

	Mister Micawber  +  302764 Mon, 11 Dec 06 10:31 AM In this kind of situation, the m-dash is merely less formal than the colon.  Either can be used here.  The hyphen, on the other hand, serves only to separate compounded words like early-morning exercise or as a line break between syllables of a single word.
