	Avangi  +  681091 Sat, 28 Feb 09 03:55 AM Yes, you can, but in this particular case, "within" is typically used to stress that the unique features of the relationships within one group would have no bearing on those of another, for purposes of this statement.  "In" would not carry this stress.  In other words, "within" is used advisedly.

	Avangi  +  681176 Sat, 28 Feb 09 12:36 PM I wish I knew of a good source.  I'm sure other's know of one.  I learned them by listening to my mother scold me when I screwed up. Of course "in" could be used, but it has so many uses, that to start a sentence with it would not get your attention.  "In baseball, there are nine innings."  You could say, "With baseball, there are nine innings," and nobody would think you had said anything different.  (Don't make me put an "ly" on that.)  "Within each of the two major leagues, there are certain unique rules of the game, making the play slightly different than in the opposite league." (That's a mess of a sentence, but perhaps you can see the special use of "within," where "in" would not quite do the same job.) Avangi Sentences

Otherwise why would be get in a car but on a bus? You just have to learn them as you go. But on the bright side (to see the positive side of things), you will almost never me misunderstood because you chose the wrong one.   Grammar Geek Joined on Tue, Jan 10 2006 Veteran Member 19,683 Barbara, who answers in American English.
