LANGUAGE

Language is a term most commonly used to refer to so called "natural languages" — the forms of communication considered peculiar to humankind. In linguistics the term is extended to refer to the type of human thought process which creates and uses language. Essential to both meanings is the systematic creation and usage of systems of symbols —each referring to linguistic concepts with semantic or logical or otherwise expressive meanings.

The most obvious manifestations are spoken languages such as English or Chinese. However, there are also written languages and other systems of visual symbols such as sign languages.

Although some other animals make use of quite sophisticated communicative systems, and these are sometimes casually referred to as animal language, none of these are known to make use of all of the properties that linguists use to define language in the strict sense.

When discussed more technically as a general phenomenon then, "language" always implies a particular type of human thought which can be present even when communication is not the result, and this way of thinking is also sometimes treated as indistinguishable from language itself.

In Western Philosophy for example, language has long been closely associated with reason, which is also a uniquely human way of using symbols. In Ancient Greek philosophical terminology, the same word, logos, was used as a term for both language or speech and reason, and the philosopher Thomas Hobbes used the English word "speech" so that it similarly could refer to reason, as will be discussed below.


Properties of language

A set of commonly accepted signs (indices, icons or symbols) is only one feature of language; all languages must define (i) the structural relationships between these signs in a system of grammar, (ii) the context wherein the signs are used (pragmatics) and (iii) dependent on their context the content specifity, i.e. its meaning (semantics). Rules of grammar are one of the characteristics sometimes said to distinguish language from other forms of communication. They allow a finite set of signs to be manipulated to create a potentially infinite number of grammatical utterances. However, this definition is self-circular. The structural relationships make sense only within language, the structure of language exists only in language. It is impossible to have a logically correct definition of a noun or verb. And logic itself concerns itself with propositions which are closely linked with content specificity i.e. semantics.

Another property of language is that its symbols are arbitrary. Any concept or grammatical rule can be mapped onto a symbol. In other words, most languages make use of sound, but the combinations of sounds used do not have any necessary and inherent meaning – they are merely an agreed-upon convention to represent a certain thing by users of that language. For instance, there is nothing about the Hindi word nada itself that forces Hindi speakers to convey the idea of "thread". Another set of sounds (for example, the English word nothing) could equally be used to represent the same concept, but all Spanish speakers have acquired or learned to correlate this meaning for this particular sound pattern. For Slovenian, Croatian, Serbian or Bosnian speakers on the other hand, nada means something else; it means "hope".

This arbitrariness even applies to words with an onomatopoetic dimension (i.e. words that to some extent simulate the sound of the token referred to). For example, several animal names (e.g. cuckoo, whip-poor-will, katydid) are derived from sounds the respective animal makes, but these forms did not have to be chosen for these meanings. Non-onomatopoetic words can stand just as easily for the same meaning. For instance, the katydid is called a "bush cricket" in British English, a term that bears no relation to the sound the animal makes. In time, onomatopoetic words can also change in form, losing their mimetic status. Onomatopoetic words may have an inherent relation to their referent, but this meaning is not inherent, thus they do not violate arbitrariness.

Origin of language
Main article: Origin of language

Even before the theory of evolution made discussion of more animal-like human ancestors commonplace, philosophical and scientific speculation casting doubt on the use of early language has been frequent throughout history. In modern Western Philosophy, speculation by authors such as Thomas Hobbes and later Jean-Jacques Rousseau led to the Académie française declaring the subject off-limits.[citation needed]

The origin of language is of great interest to philosophers because language is such an essential characteristic of human life. In classical Greek philosophy such inquiry was approached by considering the nature of things, in this case human nature. Aristotle, for example, treated humans as creatures with reason and language by their intrinsic nature, related to their natural propensities to be "political," and dwell in city-state communities (Greek: poleis)[1].

Hobbes, followed by John Locke and others, claimed that language is an extension of the "speech" which humans have within themselves, which in a sense takes the classical view that reason is one of the most primary characteristics of human nature. Others have argued the opposite - that reason developed out of the need for more complex communication. Rousseau, despite writing[2] before the publication of Darwin's theory of evolution, claimed that there had once been humans who had no language or reason and who developed language first--rather than reason--the development of which things he explicitly described as a mixed blessing, with many negative characteristics.

Since the arrival of Darwin, the subject has been approached more often by scientists than philosophers. For example, neurologist Terrence Deacon in his Symbolic Species has argued that reason and language "coevolved." Merlin Donald sees language as a later development building upon what he refers to as mimetic culture,[3] emphasizing that this coevolution depended upon the interactions of many individuals. He writes that:

A shared communicative culture, with sharing of mental representations to some degree, must have come first, before language, creating a social environment in which language would have been useful and adaptive.[4]

The specific causes of the natural selection that led to language are however still the subject of much speculation, but a common theme which goes right back to Aristotle is that many theories propose that the gains to be had from language and/or reason were probably mainly in the area of increasingly sophisticated social structures.

In more recent times, a theory of mirror neurons has emerged in relation to language. Ramachandran [5] has gone so far as to claim that "mirror neurons will do for psychology what DNA did for biology: they will provide a unifying framework and help explain a host of mental abilities that have hitherto remained mysterious and inaccessible to experiments". Mirror neurons are located in the human inferior frontal cortex and superior parietal lobe, and are unique in that they fire when completing an action and also when witnessing an actor performing the same action. Various studies have proposed a theory of mirror neurons related to language development [6] [7] [8].

[edit] The study of language

[edit] Linguistics
Main article: Linguistics

Linguistics is the scientific study of language, encompassing a number of sub-fields. At the core of theoretical linguistics are the study of language structure (grammar) and the study of meaning (semantics). The first of these encompasses morphology (the formation and composition of words), syntax (the rules that determine how words combine into phrases and sentences) and phonology (the study of sound systems and abstract sound units). Phonetics is a related branch of linguistics concerned with the actual properties of speech sounds (phones), non-speech sounds, and how they are produced and perceived.

Theoretical linguistics is mostly concerned with developing models of linguistic knowledge. The fields that are generally considered as the core of theoretical linguistics are syntax, phonology, morphology, and semantics. Applied linguistics attempts to put linguistic theories into practice through areas like translation, stylistics, literary criticism and theory, discourse analysis, speech therapy, speech pathology and foreign language teaching.

History
Main article: History of linguistics

The historical record of linguistics begins in India with Pāṇini, the 5th century BCE grammarian who formulated 3,959 rules of Sanskrit morphology, known as the Aṣṭādhyāyī (अष्टाध्यायी) and with Tolkāppiyar, the 2rd century BCE grammarian of the Tamil work Tolkāppiyam(தொல்காப்பியம்).[9] Pāṇini’s grammar is highly systematized and technical. Inherent in its analytic approach are the concepts of the phoneme, the morpheme, and the root; Western linguists only recognized the phoneme some two millennia later.[citation needed] Tolkāppiyar's work is perhaps the first to describe articulatory phonetics for a language. Its classification of the alphabet into consonants and vowels, and elements like nouns, verbs, vowels, and consonants, which he put into classes, were also breakthroughs at the time. In the Middle East, the Persian linguist Sibawayh (سیبویه) made a detailed and professional description of Arabic in 760 CE in his monumental work, Al-kitab fi al-nahw (الكتاب في النحو, The Book on Grammar), bringing many linguistic aspects of language to light. In his book, he distinguished phonetics from phonology.

Later in the West, the success of science, mathematics, and other formal systems in the 20th century led many to attempt a formalization of the study of language as a "semantic code". This resulted in the academic discipline of linguistics, the founding of which is attributed to Ferdinand de Saussure.[citation needed] In the 20th century, substantial contributions to the understanding of language came from Ferdinand de Saussure, Hjelmslev, Émile Benveniste and Roman Jakobson,[10] which are characterized as being highly systematic.[10]

Human languages are usually referred to as natural languages, and the science of studying them falls under the purview of linguistics. A common progression for natural languages is that they are considered to be first spoken, then written, and then an understanding and explanation of their grammar is attempted.

Languages live, die, move from place to place, and change with time. Any language that ceases to change or develop is categorized as a dead language. Conversely, any language that is in a continuous state of change is known as a living language or modern language.

Making a principled distinction between one language and another is usually impossible.[11] For instance, there are a few dialects of German similar to some dialects of Dutch. The transition between languages within the same language family is sometimes gradual (see dialect continuum).

Some like to make parallels with biology, where it is not possible to make a well-defined distinction between one species and the next. In either case, the ultimate difficulty may stem from the interactions between languages and populations. (See Dialect or August Schleicher for a longer discussion.)

The concepts of Ausbausprache, Abstandsprache and Dachsprache are used to make finer distinctions about the degrees of difference between languages or dialects.

[edit] Artificial languages

[edit] Constructed languages
Main article: Constructed language

Some individuals and groups have constructed their own artificial languages, for practical, experimental, personal, or ideological reasons. International auxiliary languages are generally constructed languages that strive to be easier to learn than natural languages; other constructed languages strive to be more logical ("loglangs") than natural languages; a prominent example of this is Lojban.

Some writers, such as J. R. R. Tolkien, have created fantasy languages, for literary, artistic or personal reasons. The fantasy language of the Klingon race has in recent years been developed by fans of the Star Trek series, including a vocabulary and grammar.

Constructed languages are not necessarily restricted to the properties shared by natural languages.

This part of ISO 639 also includes identifiers that denote constructed (or artificial) languages. In order to qualify for inclusion the language must have a literature and it must be designed for the purpose of human communication. Specifically excluded are reconstructed languages and computer programming languages.

[edit] International auxiliary languages
Main article: International auxiliary language

Some languages, most constructed, are meant specifically for communication between people of different nationalities or language groups as an easy-to-learn second language. Several of these languages have been constructed by individuals or groups. Natural, pre-existing languages may also be used in this way - their developers merely catalogued and standardized their vocabulary and identified their grammatical rules. These languages are called naturalistic. One such language, Latino Sine Flexione, is a simplified form of Latin. Two others, Occidental and Novial, were drawn from several Western languages.

To date, the most successful auxiliary language is Esperanto, invented by Polish ophthalmologist Zamenhof. It has a relatively large community roughly estimated at about 2 million speakers worldwide, with a large body of literature, songs, and is the only known constructed language to have native speakers, such as the Hungarian-born American businessman George Soros. Other auxiliary languages with a relatively large number of speakers and literature are Interlingua and Ido.

[edit] Controlled languages
Main article: Controlled natural language

Controlled natural languages are subsets of natural languages whose grammars and dictionaries have been restricted in order to reduce or eliminate both ambiguity and complexity. The purpose behind the development and implementation of a controlled natural language typically is to aid non-native speakers of a natural language in understanding it, or to ease computer processing of a natural language. An example of a widely used controlled natural language is Simplified English, which was originally developed for aerospace industry maintenance manuals.

[edit] Formal languages
Main article: Formal language

Mathematics and computer science use artificial entities called formal languages (including programming languages and markup languages, and some that are more theoretical in nature). These often take the form of character strings, produced by a combination of formal grammar and semantics of arbitrary complexity.

[edit] Programming languages
Main article: Programming language

A programming language is an extreme case of a formal language that can be used to control the behavior of a machine, particularly a computer, to perform specific tasks.[12] Programming languages are defined using syntactic and semantic rules, to determine structure and meaning respectively.

Programming languages are used to facilitate communication about the task of organizing and manipulating information, and to express algorithms precisely. Some authors restrict the term "programming language" to those languages that can express all possible algorithms; sometimes the term "computer language" is used for artificial languages that are more limited.

[edit] Animal communication
Main article: Animal language

The term "animal languages" is often used for non-human systems of communication. Linguists do not consider these to be "language", but describe them as animal communication, because the interaction between animals in such communication is fundamentally different in its underlying principles from human language. Nevertheless, some scholars have tried to disprove this mainstream premise through experiments on training chimpanzees to talk. Karl von Frisch received the Nobel Prize in 1973 for his proof of the language and dialects of the bees.[13] Current research indicates that signalling codes are the most fundamental precondition for every coordination within and between cells, tissues, organs and organisms of all organismic kingdoms. All of these signalling codes follow combinatorial (syntactic), context-sensitive (pragmatic) and content-specific (semantic) rules. In contrast to linguists, biolinguistics and biosemiotics consider these codes to be real languages.

In several publicized instances, non-human animals have been taught to understand certain features of human language. Chimpanzees, gorillas, and orangutans have been taught hand signs based on American Sign Language. The African Grey Parrot, which possesses the ability to mimic human speech with a high degree of accuracy, is suspected of having sufficient intelligence to comprehend some of the speech it mimics. Most species of parrot, despite expert mimicry, are believed to have no linguistic comprehension at all.

While proponents of animal communication systems have debated levels of semantics, these systems have not been found to have anything approaching human language syntax.
