Formal languages are used as tools in multiple disciplines. However, formal language theory rarely concerns itself with particular languages (except as examples), but is mainly concerned with the study of various types of formalisms to describe languages. For instance, a language can be given as those strings generated by some formal grammar;
Rudolph Carnap defined the meaning of the adjective formal in 1934 as follows: "A theory, a rule, a definition, or the like is to be called formal when no reference is made in it either to the meaning of the symbols (for example, the words) or to the sense of the expressions (e.g. the sentences), but simply and solely to the kinds and order of the symbols from which the expressions are ...
A formal grammar describes which strings from an alphabet of a formal language are valid according to the language's syntax. A grammar does not describe the meaning of the strings or what can be done with them in whatever context—only their form. A formal grammar is defined as a set of production rules for such strings in a formal language.
Words in one class can sometimes be derived from those in another. This has the potential to give rise to new words. For example, the noun aerobics has given rise to the adjective aerobicized. [3] Words combine to form phrases. A phrase typically serves the same function as a word from some particular word class. [3]
Terminology differs from lexicography, as it involves the study of concepts, conceptual systems and their labels (terms), whereas lexicography studies words and their meanings. Terminology is a discipline that systematically studies the "labelling or designating of concepts" particular to one or more subject fields or domains of human activity.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. [1] Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. [2]
Officialese, bureaucratese, [1] [2] or governmentese is language that sounds official. [3] It is the "language of officialdom". [4] Officialese is characterized by a preference for wordy, long sentences; complex words, code words, or buzzwords over simple, traditional ones; vagueness over directness; and passive over active voice [3] [5] (some of those elements may, however, vary between ...
Some proponents of Saussure's view of language have advocated a formal approach that studies language structure by identifying its basic elements and then by presenting a formal account of the rules according to which the elements combine in order to form words and sentences.
