A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which potential ...
This means the symbols within the constituent function together as a single unit and behave in the same way as other elements of their category within the sentence structure. By following these relationships, it systematically breaks down the tree, starting from the root S and moving downward through its branches until all parts of the sentence ...
To this end, he organized Harris's methods in a different way. [note 18] To describe sentence forms and structures, he came up with a set of recursive rules. These are rules that refer back to themselves. He also found that there were many different ways of presenting the grammar. He tried to develop a method to measure how simple a grammar is.
A major sentence is a regular sentence; it has a subject and a predicate, e.g. "I have a ball." In this sentence, one can change the persons, e.g. "We have a ball." However, a minor sentence is an irregular type of sentence that does not contain a main clause, e.g. "Mary!", "Precisely so.", "Next Tuesday evening after it gets dark."
The dependency relation, in contrast, is a one-to-one relation; for every word in the sentence, there is exactly one node in the syntactic structure that corresponds to that word. The distinction is illustrated with the following trees: The constituency tree on the left could be generated by phrase structure rules. The sentence S is broken down ...
Physiographic Map from "Geography of Ohio," published in 1923. During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a portmanteau of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline.
A complex sentence has one or more dependent clauses (also called subordinate clauses). Since a dependent clause cannot stand on its own as a sentence, complex sentences must also have at least one independent clause. In short, a sentence with one or more dependent clauses and at least one independent clause is a complex sentence.
The terminal yield of a surface structure tree, the surface form, is then predicted to be a grammatical sentence of the language being studied. The role and significance of deep structure changed a great deal as Chomsky developed his theories, and since the mid-1990s deep structure no longer features at all [6] (see minimalist program).
