Expert verify Lexical semantics date May 2008 linguistics Lexical semantics is a subfield of linguistics linguistic semantics . It is the study of how and what the words of a language denote Pustejovsky, 1995 . Words may either be taken to denote things in the world, or concept s, depending on the particular approach to lexical semantics. The units of meaning in lexical semantics are lexical unit s, which a speaker can continually add to throughout their life, learning new word s and their meanings. By contrast, one can only easily learn the grammatical rules of one s native language during a critical period when one is young. Lexical semantics covers theories of the classification and decomposition of word meaning, the differences and similarities in lexical semantic structure between different languages, and the relationship of word meaning to Sentence linguistics sentence meaning and syntax . One question that lexical semantics explores is whether the meaning of a lexical unit is established ... with in natural sentences , or if the meaning is already locally contained in the lexical unit. Another topic that is explored is the mapping of words to concepts.

Lexical items or lexical unit , lexical entry are a single word or chain of words that are the basic elements of a language s lexicon vocabulary . Examples are cat , traffic light , take care of , by the way , and it s raining cats and dogs . Lexical items are those which can be generally understood to convey a single meaning, much as a lexeme , but are not limited to single words. Lexical items are like seme semantics semes in that they are natural units translating between languages, or in learning a new language. In this last sense, it is sometimes said that language consists of grammaticalized lexis, and not lexicalized grammar. The entire store of lexical items in a language is called its lexis linguistics lexis . Lexical chunks Lexical items composed of more than one word are also sometimes called lexical chunks , gambits , lexical phrases , lexical units , lexicalized stems or speech formulae . The term polyword listemes is also sometimes used. Common types of lexical chunks include ref M. Lewis 1997 . Implementing the Lexical Approach , Language Teaching Publications , Hove, England ref Word s, e.g., cat , tree . Phrasal verb s, such as put off or get out . Polyword s, e.g., by the way , inside out . Collocation s, e.g., motor vehicle , absolutely convinced .

A lexical rule is in a form of syntax syntactic rule used within many theories of natural language syntax. These rules alter the argument structures of lexicon lexical items for example verb s and declension s in order to alter their combinatory properties. Lexical rules affect in particular specific word class es and morpheme s. Moreover, they may have exceptions, do not apply across word boundaries and can only apply to underlying form s. An example of a lexical rule in spoken English is the deletion of n . This rule applies in damn and autumn , but not in hymnal . Because the rule of n deletion apparently needs information about the grammatical status of the word, it can only be lexical. Lexical rules are the inverse of postlexical rule s.

Unreferenced stub auto yes date December 2009 The lexical definition of a term, also known as the dictionary definition, is the Meaning linguistic meaning of the term in common usage. As its other name implies, this is the sort of definition one is likely to find in the dictionary. A lexical definition is usually the type expected from a request for definition, and it is generally expected that such a definition will be stated as simply as possible in order to convey information to the widest audience. Note that a lexical definition is descriptive , reporting actual usage within speakers of a language , and changes with changing usage of the term, rather than prescriptive , which would be to stick with a version regarded as correct regardless of drift in accepted meaning. They tend to be inclusive, attempting to capture everything the term is used to refer to, and as such are often too vague for many purposes. When the breadth or vagueness of a lexical definition is unacceptable, a precising definition or a stipulative definition is often used. Words can be classified as lexical or nonlexical.

Unreferenced date November 2006 In computer science , a lexical grammar can be thought of as the Syntax programming languages syntax of Token parser tokens . That is, the rules governing how a character sequence is divided up into subsequences of characters, each part of which represents an individual token. For instance, the lexical grammar for many programming language s specifies that a string starts with a tt tt character and continues until a matching tt tt is found, that an identifier is a sequence of letters and digits, and that a number is a sequence of digits. So in the following character sequence tt abc xyz1 23 tt the tokens are string , identifier and number because the space character terminates the sequence of characters forming the identifier.

Lexical substitution is the task of identifying a substitute for a word in the context of a Sentence linguistics sentence . For instance, given the following sentence After the match , replace any remaining uid de cit to prevent chronic dehydration throughout the tournament , a substitute of game might be given. Lexical substitution is strictly related to Word Sense Disambiguation WSD , in that both aim to determine the meaning of a word. However, while WSD consists of automatically assigning the appropriate word sense sense from a fixed sense inventory, lexical substitution does not impose any constraint on which substitute to choose as the best representative for the word in context. By not prescribing the inventory, lexical substitution overcomes the issue of the granularity of sense distinctions and provides a level playing field for automatic systems that automatically acquire word senses a task referred to as Word Sense Induction .

wikify date November 2009 The Lexical Approach is a method of language education teaching foreign languages described by M. Lewis in the 1990s. The basic concept on which this approach rests is the idea that an important part of learning a language consists of being able to understand and produce lexical phrase s as chunks. Students are thought to be able to perceive patterns of language grammar as well as have meaningful set uses of words at their disposal when they are taught in this way. In the lexical approach, instruction focuses on fixed expressions that occur frequently in dialogues, which Lewis claims make up a larger part of discourse than unique phrases and sentences. Vocabulary is prized over grammar per se in this approach. The teaching of chunks and set phrases has become common in English as a foreign or second language English as a second or foreign language , though this is not necessarily primarily due to the Lexical Approach. In a review of the approach, Dieter Kranz wrote, The Lexical Approach can be summarized in a few words language consists not of traditional grammar and vocabulary but often of multi word prefabricated chunks TESL EJ November 1997 Volume 3, Number 1 . He goes on to list the main principles of the approach 1. The grammar vocabulary dichotomy is invalid. 2. Collocation is used as an organizing principle. 3. Successful language is a wider concept than accurate language. 4. The Observe Hypothesise Experiment cycle replaces the Present Practise Produce Paradigm. 5.

In linguistics , lexical similarity is a measure of the degree to which the word sets of two given language s are similar. A lexical similarity of 1 or 100 would mean a total overlap between vocabularies, whereas 0 means there are no common words. There are different ways to define the lexical similarity and the results vary accordingly. For example, Ethnologue s method of calculation consists in comparing a standardized set of wordlists and counting those forms that show similarity in both form and meaning. Using such a method, English language English was evaluated to have a lexical similarity of 60 with German language German and 27 with French language French . Lexical similarity can be used to evaluate the degree of Language family genetic relationship between two languages. Percentages higher than 85 usually indicate that the two languages being compared are likely to be related dialect s. The lexical similarity is only one indication of the mutual intelligibility of the two languages, since the latter also depends on the degree of phonetical, morphological, and syntactical similarity ..., lexical similarity between French and English is considerable in lexical fields relating to culture ..., lexical similarity can only be symmetrical.

In historical linguistics , lexical diffusion is both a phenomenon and a theory. The phenomenon is that by which a phoneme is modified in a subset of the lexicon, and spreads gradually to other lexical items. For example, in English language English , IPA u has changed to IPA in good and hood but not in food some dialects have it in hoof and roof but others do not in flood and blood it happened early enough that the words were affected by the change of IPA to IPA , which is now no longer productivity linguistics productive . The related theory, proposed by William Wang in 1969 is that all sound changes originate in a single word or a small group of words and then spread to other words with a similar phonological make up, but may not spread to all words in which they potentially could apply. The theory of lexical diffusion stands in contrast to the Neogrammarian hypothesis that a given sound change applies simultaneously to all words in which its context is found. William Labov , in Principles of Linguistic Change , takes the position that there are two types of sound changes regular sound change respecting the Neogrammarian hypothesis and lexical diffusion. Labov lists a typology, according to which certain phenomena are typically or exclusively regular example, vowel quality changes , while others example, metathesis, or vowel shortening tend to follow a lexical diffusion pattern. Paul Kiparsky , in the Handbook of Phonology Goldsmith editor , argues that under a proper definition of analogy as optimization, lexical diffusion is not a type of sound change. Instead, Kiparsky claims it is similar to leveling, in that it is a non proportional type of analogy.

Any event, state, process, or action a verb expresses collectively, any eventuality may also be said to have the same lexical aspect. Lexical aspect is distinguished from grammatical aspect lexical aspect is an inherent property of a semantic eventuality, whereas grammatical aspect is a property of a syntactic or morphological realization. Lexical aspect is invariant, while grammatical aspect can be changed according to the whims of the speaker.

By contrast, sitting can merely stop unless we add more details, it makes no sense to say that someone finished sitting. This is a distinction of lexical aspect between the two verbs.

unreferenced date December 2006 A lexical gap or lacuna is an absence of a word in a particular language . Types of lexical gaps include untranslatability and missing inflection s. Untranslatability Often a concept lexicalized in one language does not have a corresponding lexical unit in another language and thus presents a translation difficulty. Circumlocution , a descriptive phrase, must be used instead, or possibly even multiple phrases used in varying situations. For example, Romanian language Romanian lacks the word shallow . Therefore, shallow waters is mainly translated as ape pu in ad nci not so deep waters or ap mic small water in TV subtitles. In most languages, if the missing concept is important or must be cited often, loanword borrowing from one language and adding to another may occur. This case should not be confused with translation into a different type of lexical unit. For example, a simple word may be translated as a Compound linguistics compound or a collocation , as in the cases of the Russian word bosoy , which is translated as the compound barefoot in English, and the English word private rank private in the sense of a military rank , which is soldato semplice in Italian. An abundant source of lexical gaps used to be a contact of primitive culture s with more advanced civilization s.

These words fall into three main classes proper nouns refer exclusively to the place, object or person named, i.e. nomenclature or a name naming system concrete nouns refer to physical objects and abstract nouns refer to concepts and ideas. Other than lexical words, the lexicon consists of functional or grammatical words which do not refer to objects in the world. Discussion Language is more than a functional system for naming things. Most lexical words refer to class philosophy classes of things e.g. animals or insects or to concept s e.g. nonhuman . Depending on the degree of specialisation, language may create a taxonomy or simple categories, but the act of creating a group by reference to one or more similarities, breaks the natural link between a name and its reality. Hence, copse is more than tree and less than forest and, as spatial areas, both copses and forests contain more than trees. In semiotics , the initial view was that language creates perception s of reality . By giving salience semiotics salience to particular characteristics by naming them, the community is differentiating things from their context. Then, by making a qualitative judgement of sameness , all things sharing those characteristics may be considered the same. This creates a form of metareality.

The lexical decision task LDT is a procedure used in many psychology and psycholinguistics experiments. The basic procedure involves measuring how quickly people classify stimuli as words or nonwords. Although versions of the task had been used by researchers for a number of years, the term lexical decision task was coined by David E. Meyer and Roger W. Schvaneveldt , who brought the task to prominence in a series of studies on the structure of semantic memory in the early 1970s. Since then, the task has been used in thousands of studies, investigating semantic memory and lexical access in general. The task Subjects are presented, either visually or auditorily, with a mixture of words and logatome s or pseudoword s nonsense strings that respect the phonotactics phonotactic rules of a language, like trud in English . Their task is to indicate, usually with a button press, whether the presented stimulus is a word or not. The analysis is based on the reaction time s and, secondarily, the error rate s for the various condition experimental psychology conditions for which the words or the pseudowords differ. A very common effect is that of lexical frequency frequency words that are more frequent are recognized faster. In a cleverly designed experiment, one can draw theoretical inferences from differences like this. For instance, we might conclude that common words have a stronger mental representation than uncommon words. Lexical decision tasks are often combined with other experimental techniques, such as priming psychology priming , in which the subject is primed with a certain stimulus before the actual lexical decision task has to be performed. In this way, it has been shown that subjects are faster to respond to words when they are first shown a semantics semantically related ... http www.essex.ac.uk psychology experiments lexical.html Online Lexical Decision Experiment from ... nl Lexicale decisie no Lexical Decision ... more details
Lexical field theory , or word field theory , was introduced on March 12, 1931 by the German linguist Jost Trier . Trier argued that words acquired their meaning through their relationships to other words within the same word field. An extension of the sense of one word narrows the meaning of neighbouring words, with the words in a field fitting neatly together like a mosaic. If a single word undergoes a semantic change , then the whole structure of the lexical field changes. Trier s theory assumes that lexical fields are easily definable closed sets , ref David Kronenfeld and Gabriella Rundblad in Regine Eckardt, Klaus von Heusinger, Christoph Schwarze, Words in Time , Walter de Gruyter, 2003, p68. ISBN 3110176750 ref with no overlapping meanings or gaps. These assumptions have been questioned and the theory has been modified since its original formulation. ref Richard M.
