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.
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:
Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. All oral languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with phoneme. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific.
Autosegmental phonology is a framework of phonological analysis proposed by John Goldsmith in his PhD thesis in 1976 at the Massachusetts Institute of Technology (MIT).
Sandhi is a cover term for a wide variety of sound changes that occur at morpheme or word boundaries. Examples include fusion of sounds across word boundaries and the alteration of one sound depending on nearby sounds or the grammatical function of the adjacent words. Sandhi belongs to morphophonology.
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."
Kirundi, also known as Rundi, is a Bantu language and the national language of Burundi. It is a dialect of Rwanda-Rundi dialect continuum that is also spoken in Rwanda and adjacent parts of Tanzania, the Democratic Republic of the Congo, Uganda, as well as in Kenya. Kirundi is mutually intelligible with Kinyarwanda, the national language of Rwanda, and the two form parts of the wider dialect continuum known as Rwanda-Rundi.
Meeussen's rule is a special case of tone reduction. It was first described in Bantu languages, but occurs in analyses of other languages as well, such as Papuan languages. The tonal alternation it describes is the lowering, in some contexts, of the last tone of a pattern of two adjacent High tones (HH), resulting in the pattern HL. The phenomenon is named after its first observer, the Belgian Bantu specialist A. E. Meeussen (1912–1978). In phonological terms, the phenomenon can be seen as a special case of the Obligatory Contour Principle.
The phonology of Japanese features a phonemic inventory of about 15 consonants, plus a five-vowel system of commonly seen in other languages. There is a relatively simple phonotactic distribution of phonemes, allowing for few consonant clusters. Traditionally, autochthonous Japanese linguistics has described the language as having a unit of timing called the mora, with each mora taking up about the same length of time. In this way, the disyllabic may be analyzed as, dissected into four moras:, ,, and.
In theoretical linguistics, underspecification is a phenomenon in which certain features are omitted in underlying representations. Restricted underspecification theory holds that features should only be underspecified if their values are predictable. For example, in most dialects of English, all front vowels are unrounded. It is not necessary for these phonemes to include the distinctive feature [−round], because all [−back] vowels are [−round] vowels, so the roundness feature is not distinctive for front vowels. Radical underspecification theory, on the other hand, also allows for traditionally binary features to be specified for only one value, where it is assumed that every segment not specified for that value has the other value. For example, instead of the features [+voice] and [−voice], only [+voice] is specified and voicelessness is taken as the default.
Nonconcatenative morphology, also called discontinuous morphology and introflection, is a form of word formation and inflection in which the root is modified and which does not involve stringing morphemes together sequentially.
A floating tone is a morpheme or element of a morpheme that contains neither consonants nor vowels, but only tone. It cannot be pronounced by itself but affects the tones of neighboring morphemes.
Like most other Niger–Congo languages, Sesotho is a tonal language, spoken with two basic tones, high (H) and low (L). The Sesotho grammatical tone system is rather complex and uses a large number of "sandhi" rules.
David Arnold Odden is professor emeritus of Linguistics at the Ohio State University. His contributions to linguistics have been in the area of phonology and language description, most notably African tone and the description of Bantu languages. In addition, his work on the obligatory contour principle (OCP) has been instrumental to an understanding of that phenomenon. He is the former editor of Studies in African Linguistics and a current editorial board member of Natural Language and Linguistic Theories.
George Nickerson Clements was an American linguist specializing in phonology.
Charles Reiss is an American linguistics professor teaching at Concordia University in Montreal.
In linguistics, Optimality Theory 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, which typically use rules rather than constraints. However, phonological models of representation, such as autosegmental phonology, prosodic phonology, and linear phonology (SPE), are equally compatible with rule-based and constraint-based models. OT views 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.
Moira Yip is a British-American linguist.
Iris Berent is an Israeli-American cognitive psychologist. She is a Professor of Psychology at Northeastern University and the director of the Language and Mind Lab. She is among the founders of experimental phonology—a field that uses the methods of experimental psychology and neuroscience to study phonological competence. She has also explored the role of phonological competence in reading ability and dyslexia. Her recent work has examined how laypeople reason about innate knowledge, such as universal grammar.
