Noreen: I'm sorry but that's completely inaccurate.

The only word 'crack' of English origin is that which means crevice or sharp sound etc.

The word 'craic', however, meaning good fun etc, is entirely of Irish Gaelic origin. Just check any Irish language dictionary or any dictionary of English etymology.

Maybe we can continue the discussion in Port an Phéire, or even write a song for the craic!!
