Sentence diagramming

Lewis's explanation is better than I could give. Perhaps Tolley has a better explanation.

The diagram is useful in that it allows you to visualize the entire sentence structure at a glance. What is very easy to do with a pencil and paper is remarkably hard to do on a computer. I have not found the little lines you can draw in Word or Excel to be satisfactory for this purpose. Visio works, but is still somewhat sloppy. My greatest success, strangely, has been using the symbolic logic editor that comes with a higher-level math program I use professionally.And of course, none of these graphics can be pasted into the text-centric HTML of this forum.

Sanjay, start by diagramming simple sentences. As you get used to the basic symbols, try more complex sentences. Eventually, you will be able to do it in your head.
