Optimality Theory
In linguistics, Optimality Theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the optimal satisfaction of conflicting constraints. OT differs from other approaches to phonological analysis, such as autosegmental phonology and linear phonology (SPE), which typically use rules rather than constraints. OT models grammars as systems that provide mappings from inputs to outputs; typically, the inputs are conceived of as underlying representations, and the outputs as their surface realizations. It is an approach within the larger framework of generative grammar. In linguistics, Optimality Theory has its origin in a talk given by Alan Prince and Paul Smolensky in 1991 which was later developed in a book manuscript by the same authors in 1993. Overview There are three basic components of the theory: * Generator () takes an input, and generates the list of possible outputs, or candidates, * Constraint component () provides ...

Linguistics
Linguistics is the scientific study of human language. It is called a scientific study because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language, particularly its nature and structure. Linguistics is concerned with both the cognitive and social aspects of language. It is considered a scientific field as well as an academic discipline; it has been classified as a social science, natural science, cognitive science,Thagard, PaulCognitive Science, The Stanford Encyclopedia of Philosophy (Fall 2008 Edition), Edward N. Zalta (ed.). or part of the humanities. Traditional areas of linguistic analysis correspond to phenomena found in human linguistic systems, such as syntax (rules governing the structure of sentences); semantics (meaning); morphology (structure of words); phonetics (speech sounds and equivalent gestures in sign languages); phonology (the abstract sound system of a particular language); and pragmatics (how social con ...

Metathesis (linguistics)
Metathesis (; from Greek , from "I put in a different order"; Latin: ''transpositio'') is the transposition of sounds or syllables in a word or of words in a sentence. Most commonly, it refers to the interchange of two or more contiguous segments or syllables, known as adjacent metathesis or local metathesis: * ''foliage'' > ''**foilage'' (adjacent segments) * ''anemone'' > ''**anenome'' (adjacent syllables) * ''cavalry'' > ''**calvary'' (codas of adjacent syllables) Metathesis may also involve interchanging non-contiguous sounds, known as nonadjacent metathesis, long-distance metathesis, or hyperthesis, as shown in these examples of metathesis sound change from Latin to Spanish: * Latin > Spanish "word" * Latin > Spanish "miracle" * Latin > Spanish "danger, peril" * Latin > Spanish "crocodile" Many languages have words that show this phenomenon, and some even use it as a regular part of their grammar, such as Hebrew and Fur. The process of metathesis has altered the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distinctive Feature
In linguistics, a distinctive feature is the most basic unit of phonological structure that distinguishes one sound from another within a language. For example, the feature oicedistinguishes the two bilabial plosives: and There are many different ways of defining and arranging features into ''feature systems'': some deal with only one language while others are developed to apply to all languages. Distinctive features are grouped into categories according to the natural classes of segments they describe: major class features, laryngeal features, manner features, and place features. These feature categories in turn are further specified on the basis of the phonetic properties of the segments in question. For phonemes to be in a particular natural class, they have to share the same distinctive features such as articulation and/or sound similar to each other. We can find distinctive features between two words by finding the minimal pair between them. The minimal pair are when two ...

Reduplication
In linguistics, reduplication is a morphological process in which the root or stem of a word (or part of it) or even the whole word is repeated exactly or with a slight change. The classic observation on the semantics of reduplication is Edward Sapir's: "generally employed, with self-evident symbolism, to indicate such concepts as distribution, plurality, repetition, customary activity, increase of size, added intensity, continuance." Reduplication is used in inflections to convey a grammatical function, such as plurality, intensification, etc., and in lexical derivation to create new words. It is often used when a speaker adopts a tone more "expressive" or figurative than ordinary speech and is also often, but not exclusively, iconic in meaning. Reduplication is found in a wide range of languages and language groups, though its level of linguistic productivity varies. Reduplication is found in a wide variety of languages, as exemplified below. Examples of it can be found at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
