It's a response when someone says something that is not important or relevant to the discussion. "John has applied for the scholarship. His grades really aren't that outstanding. He doesn't do any community service. What do you think of his suitability for the scholarship? "Well, he really dresses neatly." "That's neither here nor there. We should focus on his academic abilities."

self explanatory................

a tourist- A came to America and he wants to go to an important site where there is a statue.he is told that it is in new- york city or in washington dc.so A reaches at new-york city and he asks a native B-"is that statue here in new-york or in is it in washinton dc?". but B says:"That's neither here(in new-york city) nor there(washington dc) but it is in chicago."ok.

ne burda ne orda!
