Metathesis may refer to:
- Metathesis (linguistics)Metathesis (linguistics)Metathesis is the re-arranging of sounds or syllables in a word, or of words in a sentence. Most commonly it refers to the switching of two or more contiguous sounds, known as adjacent metathesis or local metathesis:...
, in phonologyPhonologyPhonology is, broadly speaking, the subdiscipline of linguistics concerned with the sounds of language. That is, it is the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use...
, a sound change that alters the order of phonemes in a word- Quantitative metathesisQuantitative metathesisQuantitative metathesis is a specific form of metathesis or transposition involving quantity or vowel length...
, a situation in which two vowel sounds follow directly one after the other and a transposition of vowel length takes place
- Quantitative metathesis
- Metathesis reaction, in chemistry, a bimolecular process involving the exchange of bonds between the two reacting chemical species
- Olefin metathesisOlefin metathesisOlefin metathesis or transalkylidenation is an organic reaction that entails redistribution of alkylene fragments by the scission of carbon - carbon double bonds in olefins . Its advantages include the creation of fewer sideproducts and hazardous wastes. Yves Chauvin, Robert H. Grubbs, and Richard R...
, an organic reaction which involves redistribution of olefinic (alkene) bonds - Alkane metathesisAlkane metathesisAlkane metathesis is a chemical reaction in which alkanes are rearranged to give longer or shorter alkane products. It is similar to olefin metathesis, except that olefin metathesis cleaves and recreates a carbon-carbon double bond, but alkane methathesis operates on a carbon-carbon single...
, a chemical reaction in which alkanes are rearranged to give longer or shorter alkane products - Alkyne metathesisAlkyne metathesisAlkyne metathesis is an organic reaction involving the redistribution of alkyne chemical bonds. This reaction is closely related to olefin metathesis. Metal-catalyzed alkyne metathesis was first described in 1968 by Bailey, et al. The Bailey system utilized a mixture of tungsten and silicon oxides...
