A simple descriptivist theory may further hold that the meaning of a sentence S that contains p is given by the collection of sentences produced by replacing each instance of p in S with one of the descriptions in D. So, the sentence such as "Saul Kripke stands next to a table" has the same meaning as the following collection of sentences:
[1] [2] It contains the now-famous sentence "Colorless green ideas sleep furiously", [3] which Chomsky offered as an example of a grammatically correct sentence that has no discernible meaning, thus arguing for the independence of syntax (the study of sentence structures) from semantics (the study of meaning). [4] [note 1]
In linguistics, syntax (/ ˈ s ɪ n t æ k s / SIN-taks) [1] [2] is the study of how words and morphemes combine to form larger units such as phrases and sentences.Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), [3] agreement, the nature of crosslinguistic variation, and the relationship between form and meaning ().
The pragmatic naming theory of Charles Sanders Peirce is sometimes considered a precursor of causal-historical naming theory. He described proper names in the following terms: "A proper name, when one meets with it for the first time, is existentially connected with some percept or other equivalent individual knowledge of the individual it names.
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."
X-bar theory was an important step forward because it simplified the description of sentence structure. Earlier approaches needed many phrase structure rules, which went against the idea of a simple, underlying system for language. X-bar theory offered a more elegant and economical solution, aligned with the thesis of generative grammar.
A satisfiable theory is a theory that has a model. This means there is a structure M that satisfies every sentence in the theory. Any satisfiable theory is syntactically consistent, because the structure satisfying the theory will satisfy exactly one of φ and the negation of φ, for each sentence φ.
In a deductive theory, any sentence which is a logical consequence of one or more of the axioms is also a sentence of that theory. [11] This is called the received view of theories. In the semantic view of theories, which has largely replaced the received view, [18] [19] theories are viewed as scientific models. A model is an abstract and ...
