Language ideology (also referred to as linguistic ideology) is a concept used primarily within the fields of anthropology, sociolinguistics, and cross-cultural studies to characterize any set of beliefs or feelings about languages as used in their social worlds. When recognized and explored, language ideologies expose connections between the beliefs speakers have about language and the larger social and cultural systems they are a part of, illustrating how these beliefs are informed by and rooted in such systems. By doing so, language ideologies link the implicit as well as explicit assumptions people have about a language or language in general to their social experience and political as well as economic interests. Language planning is a deliberate effort to influence the function, structure, or acquisition of languages or language variety within a speech community. It is often associated with government planning, but is also used by a variety of non-governmental organizations, such as grass-roots organizations and even individuals. The goals of language planning differ depending on the nation or organization, but generally include making planning decisions and possibly changes for the benefit of communication. Planning or improving effective communication can also lead to other social changes such as language shift or assimilation, thereby providing another motivation to plan the structure, function and acquisition of languages. Corpus planning refers to the prescriptive intervention in the forms of a language, whereby planning decisions are made to engineer changes in the structure of the language.Corpus planning activities often arise as the result of beliefs about the adequacy of the form of a language to serve desired functions. Unlike status planning, which is primarily undertaken by administrators and politicians, corpus planning generally involves planners with greater linguistic expertise.There are three traditionally recognized types of corpus planning: graphization, standardization, and modernization. In linguistics, language death is a process that affects speech communities where the level of linguistic competence that speakers possess of a given language variety is decreased, eventually resulting in no native or fluent speakers of the variety. Language death may affect any language idiom, including dialects and languages. Language death should not be confused with language attrition (also called language loss), which describes the loss of proficiency in a language at the individual level.
49. The definition of main terms of phonological, morphological systems. Phonology is a branch of linguistics concerned with the systematic organization of sounds in languages. It has traditionally focused largely on study of the systems of phonemes in particular languages (and therefore used to be also called phonemics, or phonematics), but it may also cover any linguistic analysis either at a level beneath the word (including syllable, onset and rhyme, articulatory gestures, articulatory features, mora, etc.) or at all levels of language where sound is considered to be structured for conveying linguistic meaning. Phonology also includes the study of equivalent organizational systems in sign languages. The word phonology (as in the phonology of English) can also refer to the phonological system (sound system) of a given language. This is one of the fundamental systems which a language is considered to comprise, like its syntax and its vocabulary.
Phonology is often distinguished from phonetics. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a given language or across languages to encode meaning. For many linguists, phonetics belongs to descriptive linguistics, and phonology to theoretical linguistics, although establishing the phonological system of a language is necessarily an application of theoretical principles to analysis of phonetic evidence. Note that this distinction was not always made, particularly before the development of the modern concept of phoneme in the mid 20th century. Some subfields of modern phonology have a crossover with phonetics in descriptive disciplines such as psycholinguistics and speech perception, resulting in specific areas like articulatory phonology or laboratory phonology. In linguistics, morphology is the identification, analysis and description of the structure of a given language's morphemes and other linguistic units, such as root words, affixes, parts of speech, intonation/stress, or implied context (words in a lexicon are the subject matter of lexicology). Morphological typology represents a method for classifying languages according to the ways by which morphemes are used in a language—from the analytic that use only isolated morphemes, through the agglutinative ("stuck-together") and fusional languages that use bound morphemes (affixes), up to the polysynthetic, which compress many separate morphemes into single words.(One of the definitions for Morphology)
While words are generally accepted as being (with clitics) the smallest units of syntax, it is clear that in most languages, if not all, words can be related to other words by rules (grammars). For example, English speakers recognize that the words dog and dogs are closely related—differentiated only by the plurality morpheme "-s", which is only foundbound to nouns, and is never separate. Speakers of English (a fusional language) recognize these relations from their tacit knowledge of the rules of word formation in English. They infer intuitively that dog is to dogs as cat is to cats; similarly, dog is to dog catcher as dish is to dishwasher, in one sense. The rules understood by the speaker reflect specific patterns, or regularities, in the way words are formed from smaller units and how those smaller units interact in speech. In this way, morphology is the branch of linguistics that studies patterns of word formation within and across languages, and attempts to formulate rules that model the knowledge of the speakers of those languages.
