In linguistics, a redundancy is information that is expressed more than once. [1] [2]
Examples of redundancies include multiple agreement features in morphology, [1] multiple features distinguishing phonemes in phonology, [2] or the use of multiple words to express a single idea in rhetoric. [1]
Redundancy may occur at any level of grammar. Because of agreement – a requirement in many languages that the form of different words in a phrase or clause correspond with one another – the same semantic information may be expressed several times. In the Spanish phrase los árboles verdes ("the green trees"), for example, the article los, the noun árboles, and the adjective verdes are all inflected to show that the phrase is plural. [1] An English example would be: that man is a soldier versus those men are soldiers.
In phonology, a minimal pair is a pair of words or phrases that differs by only one phoneme, the smallest distinctive unit of the sound system. Even so, phonemes may differ on several phonetic features. For example, the English phonemes /p/ and /b/ in the words pin and bin feature different voicing, aspiration, and muscular tension. Any one of these features is sufficient to differentiate /p/ from /b/ in English. [2]
Generative grammar uses such redundancy to simplify the form of grammatical description. Any feature that can be predicted on the basis of other features (such as aspiration on the basis of voicing) need not be indicated in the grammatical rule. Features that are not redundant and therefore must be indicated by rule are called distinctive features. [2]
As with agreement in morphology, phonologically conditioned alternation, such as coarticulation and assimilation, add redundancy on the phonological level. The redundancy of phonological rules may clarify some vagueness in spoken communication. According to psychologist Steven Pinker, "In the comprehension of speech, the redundancy conferred by phonological rules can compensate for some of the ambiguity of the sound wave. For example, a speaker may know that thisrip must be this rip and not the srip because in English the initial consonant cluster sr is illegal." [3]
Writing guides, especially for technical writing, usually advise avoiding redundancy, "especially the use of two expressions that mean the same thing. Such repetition works against readability and conciseness." [4] Others make a distinction between redundancy and repetition:
Repetition, if used well, can be a good tool to use in your writing. It can add emphasis to what you are trying to say and strengthen a point. There are many types of useful repetition. Redundancy, on the other hand, cannot be a good thing. Redundancy happens when the repetition of a word or idea does not add anything to the previous usage; it just restates what has already been said, takes up space, and gets in the way without adding meaning. [5]
Computer scientist Donald E. Knuth, author of highly acclaimed textbooks, recommends "to state things twice, in complementary ways, especially when giving a definition. This reinforces the reader's understanding." [6]
Charles Francis Hockett was an American linguist who developed many influential ideas in American structuralist linguistics. He represents the post-Bloomfieldian phase of structuralism often referred to as "distributionalism" or "taxonomic structuralism". His academic career spanned over half a century at Cornell and Rice universities. Hockett was also a firm believer of linguistics as a branch of anthropology, making contributions that were significant to the field of anthropology as well.
Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and written forms, and may also be conveyed through sign languages. The vast majority of human languages have developed writing systems that allow for the recording and preservation of the sounds or signs of language. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.
The following outline is provided as an overview and topical guide to linguistics:
A morpheme is the smallest meaningful constituent of a linguistic expression. The field of linguistic study dedicated to morphemes is called morphology.
In phonology, minimal pairs are pairs of words or phrases in a particular language, spoken or signed, that differ in only one phonological element, such as a phoneme, toneme or chroneme, and have distinct meanings. They are used to demonstrate that two phones represent two separate phonemes in the language.
In linguistics, morphology is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary.
In phonology and linguistics, a phoneme is a set of phones that can distinguish one word from another in a particular language.
In phonetics, a phone is any distinct speech sound or gesture, regardless of whether the exact sound is critical to the meanings of words.
Phonology is the branch of linguistics that studies how languages systematically organize their phones or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either:
In linguistics, transformational grammar (TG) or transformational-generative grammar (TGG) is part of the theory of generative grammar, especially of natural languages. It considers grammar to be a system of rules that generate exactly those combinations of words that form grammatical sentences in a given language and involves the use of defined operations to produce new sentences from existing ones.
Historical linguistics, also termed diachronic linguistics, is the scientific study of language change over time. Principal concerns of historical linguistics include:
Pleonasm is redundancy in linguistic expression, such as "black darkness" or "burning fire". It is a manifestation of tautology by traditional rhetorical criteria and might be considered a fault of style. Pleonasm may also be used for emphasis, or because the phrase has become established in a certain form. Tautology and pleonasm are not consistently differentiated in literature.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. 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. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
In linguistics, a grammatical category or grammatical feature is a property of items within the grammar of a language. Within each category there are two or more possible values, which are normally mutually exclusive. Frequently encountered grammatical categories include:
In linguistics, a feature is any characteristic used to classify a phoneme or word. These are often binary or unary conditions which act as constraints in various forms of linguistic analysis.
Linguistics is the scientific study of language. Linguistics is based on a theoretical as well as a descriptive study of language and is also interlinked with the applied fields of language studies and language learning, which entails the study of specific languages. Before the 20th century, linguistics evolved in conjunction with literary study and did not exclusively employ scientific methods.
Verbosity, or verboseness, is speech or writing that uses more words than necessary. The opposite of verbosity is plain language.
Peruvian Spanish is a family of dialects of the Spanish language that have been spoken in Peru since brought over by Spanish conquistadors in 1532. There are five varieties spoken in the country, by about 94.4% of the population. The five Peruvian dialects are Andean Spanish, Peruvian Coastal Spanish, Andean-Coastal Spanish, Equatorial Spanish, and Amazonic Spanish.
Sign languages such as American Sign Language (ASL) are characterized by phonological processes analogous to, yet dissimilar from, those of oral languages. Although there is a qualitative difference from oral languages in that sign-language phonemes are not based on sound, and are spatial in addition to being temporal, they fulfill the same role as phonemes in oral languages.
In literary criticism and rhetoric, a tautology is a statement that repeats an idea, using near-synonymous morphemes, words or phrases, effectively "saying the same thing twice". Tautology and pleonasm are not consistently differentiated in literature. Like pleonasm, tautology is often considered a fault of style when unintentional. Intentional repetition may emphasize a thought or help the listener or reader understand a point. Sometimes logical tautologies like "Boys will be boys" are conflated with language tautologies, but a language tautology is not inherently true, while a logical tautology always is.
