A dichotomy is any splitting of a whole into exactly two non-overlapping parts. In other words, it is a mutually exclusive bipartition of elements. i.e. nothing can belong simultaneously to both parts, and everything must belong to one part or the other. They are often contrasting and spoken of as "opposites." The term comes from dichotomos (divided): dich- ([in] two) temnein (to cut). The above applies directly when the term is used in mathematics, linguistics. For example, if there is a concept A, and it is split into parts B and not-B, then the parts form a dichotomy: they are mutually exclusive, since no part of B is contained in not-B and vice-versa, and they are jointly exhaustive, since they cover all of A, and together again give A.
One of the fundamental concepts of linguistics is the dichotomy of «language and speech» (langue—parole) introduced by F. de Saussure. According to it language is a system of elementary and complex signs-phonemes, morphemes, words, word combinations, utterances and combinations of utterances. Language as such a system exists m human minds only and linguistic forms or units can be systematise" into paradigms. language is a mentally organised system of linguistic units. An ъ0 .. aj speaker never uses it. When we use these units we mix m in acts of speech. As distinct from language speech is not relv mental phenomenon, not a system but a process of combining these linguistic elements into linear linguistic units that are called syntagmatic. The result of this process is the linear or syntagmatic combination of vowels and consonants into words, words into word-combinations and sentences and combination of sentences into texts.
