  2. Underlying representation - Wikipedia

    en.wikipedia.org/wiki/Underlying_representation

    [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.

  3. Morphophonology - Wikipedia

    en.wikipedia.org/wiki/Morphophonology

    The isolation form of a morpheme is the form in which that morpheme appears in isolation (when it is not subject to the effects of any other morpheme). In the case of a bound morpheme, such as the English past tense ending "-ed", it is generally not possible to identify an isolation form since such a morpheme does not occur in isolation.

  4. Representation (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Representation_(mathematics)

    In mathematics, a representation is a very general relationship that expresses similarities (or equivalences) between mathematical objects or structures.Roughly speaking, a collection Y of mathematical objects may be said to represent another collection X of objects, provided that the properties and relationships existing among the representing objects y i conform, in some consistent way, to ...

  5. Obligatory contour principle - Wikipedia

    en.wikipedia.org/wiki/Obligatory_Contour_Principle

    A commonly held conception within phonology is that no morpheme is allowed to contain two consecutive high tones. If two consecutive high tones appear within a single morpheme, then some rule must have applied . Maybe one of the surface high-tone vowels was underlyingly high-toned, while the other was underlyingly toneless.

  6. Morphism - Wikipedia

    en.wikipedia.org/wiki/Morphism

    A category C consists of two classes, one of objects and the other of morphisms.There are two objects that are associated to every morphism, the source and the target.A morphism f from X to Y is a morphism with source X and target Y; it is commonly written as f : X → Y or X Y the latter form being better suited for commutative diagrams.

    en.wikipedia.org/wiki/Glossary_of_mathematical...

    A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

  8. Quiver (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Quiver_(mathematics)

    In mathematics, especially representation theory, a quiver is another name for a multidigraph; that is, a directed graph where loops and multiple arrows between two vertices are allowed. Quivers are commonly used in representation theory: a representation V of a quiver assigns a vector space V ( x ) to each vertex x of the quiver and a linear ...

  9. Mirror theory - Wikipedia

    en.wikipedia.org/wiki/Mirror_theory

    Similar to mirror theory is the mirror principle of the distributed morphology framework which deals primarily with issues of affix ordering. [1] In the model of Distributed Morphology, the underlying assumption is such that all morphemes in a morphologically complex word are effectually "leaves" on a syntactic tree.
