re:Why do we say, "cross the street" rather than saying "cross street"?

Well actually i say both
Cross the street, is part of a verbal phrase, ("Cross the street with me, and walk in the shade" )
Cross street is an adjective and noun.. (The closest cross street to my office is Reade street.)

Do i use the with specific rules? no..but they are sometimes used to make things clearer.


my other obsession
