We have to give presentations on syntax. I remember awhile back reading this modernist poem which repeated the same sentence over 20 times but changed the order of words each time resulting in a different meaning. I think it really demonstrates the importance of syntax. The only problem is I don't remember what it's called...do you know what poem I'm talking about?
