Why are you using the Reed-Kellogg system?
It has been universally rejected by grammarians as illogical, confusing, and unable to cope with complex clause structures.
I strongly advise you to stick with the 'standard' system of tree-diagramming.
Oh my god, this is fantastic how can you not like it?
When I was learning grammar at one point (some time back), I always wondered if there was some kind of diagram that existed to help show the relationship between words. And then, a week ago when I accidentally stumbled across this sentence diagram tutorial, showing the relationship between AND, OR, BUT, BOTH, I was amazed. This is what I wanted to see, or wish I could have learnt at the time. The way it is structured is actually quite visual to anything I have been exposed to.
I think the argument against it is poor. I mean, people are saying it requires additional skill set to draw the diagrams on top of learning another difficult skill set - grammar. I think its poor mentality to think that way. The diagrams are quite easy to understand, enough, to visually see the connection between words.
It does look confusing at first and maybe intimidating but once you go through a few tutorials you begin to see its value.
Currently I'm learning this so cannot comment further.
The sentence tree diagram looks interesting, but it doesn’t show the visual relationship between words. I think what I’m looking for is something to show a clear relationship between words.
Not sure about the complex clause structure. I think for me, the purpose of sentence diagramming is to help understand the basic idea of putting simple sentence together so you can advance to the next level.
