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 sentence was constructed by Noam Chomsky as an illustration that phrase structure rules are capable of generating syntactically correct but semantically incorrect sentences. Phrase structure rules break sentences down into their constituent parts. These constituents are often represented as tree structures (dendrograms). The tree for ...
This sentence involves the following five PSRs: S → NP VP; NP → Det N (the man) NP → N (linguistics) AdvP → Adv (enthusiastically) VP → V NP AdvP (studies linguistics enthusiastically) With a tree diagram, the sentence's structure can be depicted as in Figure 1. Figure 1
A linguist should separate the "grammatical sequences" or sentences of a language from the "ungrammatical sequences". [9] By a "grammatical" sentence Chomsky means a sentence that is intuitively "acceptable to a native speaker". [9] It is a sentence pronounced with a "normal sentence intonation".
The two diagrams thus disagree concerning the status of do, diagrams, show, and do these diagrams show us, the phrase structure diagram showing them as constituents and the dependency grammar diagram showing them as non-constituents. To determine which analysis is more plausible, one turns to the tests for constituents discussed above.
A sentence, in turn, is formed as a sequence of symbols, beginning with a designated non-terminal symbol and culminating in a terminal string. Every terminal node is part of a constituent, as constituents form the interconnected structure leading from the root to the smallest, indivisible unit of the tree.
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."
For example, the sentences "Pat loves Chris" and "Chris is loved by Pat" mean roughly the same thing and use similar words. Some linguists, Chomsky in particular, have tried to account for this similarity by positing that these two sentences are distinct surface forms that derive from a common (or very similar [1]) deep structure.
