In some models of phonology as well as morphophonology in the field of linguistics, the underlying representation (UR) or underlying form (UF) of a word or morpheme is the abstract form that a word or morpheme is postulated to have before any phonological rules have been applied to it. [1] [2] In contrast, a surface representation is the phonetic representation of the word or sound. The concept of an underlying representation is central to generative grammar. [3]
If more phonological rules apply to the same underlying form, they can apply wholly independently of each other or in a feeding or counterbleeding order. The underlying representation of a morpheme is considered to be invariable across related forms (except in cases of suppletion), despite alternations among various allophones on the surface.
In many cases, the underlying form is simply the phonemic form. For example, in many varieties of American English, the phoneme /t/ in a word like wet can surface either as an unreleased stop [t̚] or as a flap [ɾ], depending on environment: [wɛt]wet vs. [ˈwɛɾɚ]wetter. (In both cases, however, the underlying representation of the morpheme wet is the same: its phonemic form /wɛt/.)
Phonological rules may change the phonemes involved. In such cases, pipes ("|") or double slashes may be used in transcription to distinguish the underlying form from its phonemic realization. For example, the word "cats" has the phonemic representation /kæts/. If it is assumed that the underlying form of the English plural suffix is a [z] sound, the underlying form of "cats" would be //kætz//. (The [z] surfaces as an [s] because of the phonological process of devoicing after an unvoiced consonant.)
Sandhi, such as tone sandhi in Chinese, is another phonological process that changes the phonemes of a morpheme from its underlying form.
In phonology, an allophone is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.
Morphophonology is the branch of linguistics that studies the interaction between morphological and phonological or phonetic processes. Its chief focus is the sound changes that take place in morphemes when they combine to form words.
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:
A sound change, in historical linguistics, is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound by a different one or a more general change to the speech sounds that exist, such as the merger of two sounds or the creation of a new sound. A sound change can eliminate the affected sound, or a new sound can be added. Sound changes can be environmentally conditioned if the change occurs in only some sound environments, and not others.
In linguistics, an alternation is the phenomenon of a morpheme exhibiting variation in its phonological realization. Each of the various realizations is called an alternant. The variation may be conditioned by the phonological, morphological, and/or syntactic environment in which the morpheme finds itself.
Tone sandhi is a phonological change that occurs in tonal languages. It involves changes to the tones assigned to individual words or morphemes, based on the pronunciation of adjacent words or morphemes. This change typically simplifies a bidirectional tone into a one-directional tone. Tone sandhi is a type of sandhi, which refers to fusional changes, and is derived from the Sanskrit word for "joining."
In phonetics, palatalization or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate. Consonants pronounced this way are said to be palatalized and are transcribed in the International Phonetic Alphabet by affixing the letter ⟨ʲ⟩ to the base consonant. Palatalization cannot minimally distinguish words in most dialects of English, but it may do so in languages such as Russian, Japanese, Norwegian, Võro, Irish and Kashmiri.
A phonemic orthography is an orthography in which the graphemes correspond to the language's phonemes. Natural languages rarely have perfectly phonemic orthographies; a high degree of grapheme–phoneme correspondence can be expected in orthographies based on alphabetic writing systems, but they differ in how complete this correspondence is. English orthography, for example, is alphabetic but highly nonphonemic; it was once mostly phonemic during the Middle English stage, when the modern spellings originated, but spoken English changed rapidly while the orthography was much more stable, resulting in the modern nonphonemic situation. On the contrary the Albanian, Serbian/Croatian/Bosnian/Montenegrin, Romanian, Italian, Turkish, Spanish, Finnish, Czech, Latvian, Esperanto, Korean and Swahili orthographic systems come much closer to being consistent phonemic representations.
English phonology is the system of speech sounds used in spoken English. Like many other languages, English has wide variation in pronunciation, both historically and from dialect to dialect. In general, however, the regional dialects of English share a largely similar phonological system. Among other things, most dialects have vowel reduction in unstressed syllables and a complex set of phonological features that distinguish fortis and lenis consonants.
The phonology of Japanese features a phonemic inventory of five vowels and 14 or more consonants. The phonotactics are relatively simple, allowing for few consonant clusters. Japanese phonology has been affected by the presence of several layers of vocabulary in the language: in addition to native Japanese vocabulary, Japanese has a large amount of Chinese-based vocabulary and loanwords from other languages.

In historical linguistics, phonological change is any sound change that alters the distribution of phonemes in a language. In other words, a language develops a new system of oppositions among its phonemes. Old contrasts may disappear, new ones may emerge, or they may simply be rearranged. Sound change may be an impetus for changes in the phonological structures of a language. One process of phonological change is rephonemicization, in which the distribution of phonemes changes by either addition of new phonemes or a reorganization of existing phonemes. Mergers and splits are types of rephonemicization and are discussed further below.
In phonology, voicing is a sound change where a voiceless consonant becomes voiced due to the influence of its phonological environment; shift in the opposite direction is referred to as devoicing or desonorization. Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel.
The phonology of Standard Chinese has historically derived from the Beijing dialect of Mandarin. However, pronunciation varies widely among speakers, who may introduce elements of their local varieties. Television and radio announcers are chosen for their ability to affect a standard accent. Elements of the sound system include not only the segments—e.g. vowels and consonants—of the language, but also the tones applied to each syllable. In addition to its four main tones, Standard Chinese has a neutral tone that appears on weak syllables.
A phonological rule is a formal way of expressing a systematic phonological or morphophonological process in linguistics. Phonological rules are commonly used in generative phonology as a notation to capture sound-related operations and computations the human brain performs when producing or comprehending spoken language. They may use phonetic notation or distinctive features or both.
This article covers the phonology of the Uyghur language. Uyghur, a Turkic language spoken primarily in the Xinjiang Uyghur Autonomous Region features both vowel harmony and vowel reduction.
This article aims to describe the phonology and phonetics of central Luxembourgish, which is regarded as the emerging standard.
Phonemic contrast refers to a minimal phonetic difference, that is, small differences in speech sounds, that makes a difference in how the sound is perceived by listeners, and can therefore lead to different mental lexical entries for words. For example, whether a sound is voiced or unvoiced matters for how a sound is perceived in many languages, such that changing this phonetic feature can yield a different word ; see Phoneme. Another example in English of a phonemic contrast would be the difference between leak and league; the minimal difference of voicing between [k] and [g] does lead to the two utterances being perceived as different words. On the other hand, an example that is not a phonemic contrast in English is the difference between and. In this case the minimal difference of vowel length is not a contrast in English and so those two forms would be perceived as different pronunciations of the same word seat.
