Sentence in linguistic studies

Abstract

Language is an organized thought in the core of a sound material, the purpose of which is expression and communication, and "it is a product that the speaker accepts and records, without him doing any activity in it at all, but rather his thinking in it has no activity other than the activity of arrangement to form a composition of two or more successive units, brought together by mutual contextual relationships, determined by the special grammatical system of this language that distinguishes it from other languages.

The best model that represents this composition in the linguistic study is the sentence, which is considered to be included in speech and not language in general; because the most special characteristics of speech are the freedom that a person enjoys in composing isolated linguistic structures, and attributing them to carry meaning, and convey the implication and intent. De Saussure referred to this by saying: "The sentence is the best model that represents the composition/context, but it is included in speech and not language, so does it not follow from that that the composition is also included in the word/speech"  The entire grammatical lesson is based on it in terms of its composition, patterns, and system, in terms of its nature, in terms of its parts, and in terms of what occurs to its parts during its composition in terms of advancement and delay, and of expression and concealment, and what it presents of general meanings that are conveyed by the tools of expression that are used for this purpose.
