Analysing ungrammatical sentences

[Linguist__]

I read the threads in this section in a sort of awe, and perhaps when I have more time I will learn how to diagram sentences using the Reed-Kellog method.

However, I was wondering what people's thoughts were about analysing/diagramming ungrammatical sentences.

As part of an assignment, I have to analyse sentences spoken by a seven year old child with receptive/expressive language impairment. I will give some examples of the sentences here to show the kinds of ungrammatical utterances I mean.

The context is part of an assessment where the assessor says a word, and the child must form an utterance using this word. These are all real utterances spoken by a child with language impairment.

"Until you good won't go outside"

"Unless you back I have to do this"

"A dog is younger and two other dogs"

I don't particularly want these to be analysed. I must ask my lecturer how to analyse these according the the methods we learn. But I just though it would be interesting, as the sentences being diagrammed here are often complex, perfectly structured ones.

The only way I know of to deal with an "ungrammatical" sentence with Reed-Kellogg is to supply understood words until it be grammatical.
I believe the omission of forms of the verb "to be" is quite common. Kondorosi and I considered that in Hungarian and Black English. Lack of an underlying syntax would indicate a very critical problem in the mind of the speaker of any language.
