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 ...
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 ...
The clause structure with an inverted subject and verb, used to form questions as described above, is also used in certain types of declarative sentences. This occurs mainly when the sentence begins with adverbial or other phrases that are essentially negative or contain words such as only , hardly , etc.:
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."
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 ...
grammar, a right-branching sentence is a sentence in which the main subject of the sentence is described first, and is followed by a sequence of modifiers that provide additional information about the subject. The inverse would be a Left-branching sentence. The name "right-branching" comes from the English syntax of putting such modifiers to ...
A simple sentence consists of only one clause. A compound sentence consists of two or more independent clauses. A complex sentence has at least one independent clause plus at least one dependent clause. [1] A set of words with no independent clause may be an incomplete sentence, also called a sentence fragment.
The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue (Post canonical systems). Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy : context-sensitive grammars or context-free grammars .
