Definition of metathesis in English:

metathesis

nounPlural metatheses mɪˈtaθɪsɪsməˈtæθəsəs

1Grammar
mass noun The transposition of sounds or letters in a word.
〔语法〕音位（或字位）变换，换位
he attributes the metathesis of the last two sounds to the Creole tendency to end words with a vowel
Example sentencesExamples
- We are dealing here with a phenomenon called metathesis (pronounced mih-TATH-uh-sis), the switching of two adjacent sounds within a word.
- It looks like Safire is assuming a metathesis and then a reshaping to match other cular words, which would supply a/y.
- Stress errors and phoneme substitutions or metatheses not attributable to dialect or articulation, however, were considered incorrect.
- X sometimes alternates with sk by metathesis: Manx for earlier Mansk; piskey as a variant of pixie; ax as a dialect form of ask.
2Chemistry
another term for double decomposition
Example sentencesExamples
- Recently there has also been a growing interest in utilising what is known as the alkene metathesis reaction for altering chain-lengths of ‘oils’ to form new compounds.
- I've never done an olefin metathesis reaction, which means that the trend started without me and will leave without me.
- In South Africa, interest in alkene metathesis research is growing.
- This was made by metathesis of 1-ethyl - 3-methylimidazolium [emim] with Ag [BF 4] in methanol.
- The Nobel prize in Chemistry this year goes to Robert H. Grubbs, Richard R. Schrock, and Yves Chauvin (Institut Francais du Petrole) for the development of metathesis.

Derivatives

metathetic

adjective ˌmɛtəˈθɛtɪkˌmɛdəˈθɛdɪk

Sometimes the metathetic version of a word becomes so popular that it replaces the original so-called ‘correct’ pronunciation.
Example sentencesExamples
- Here are a few more words that are metathetic forms of former words.
- There is a great deal of debate as to whether or not stimuli that are part of a metathetic continuum can be explained by the Power Law.
- The present invention relates to a heterogenic rhenium containing catalyst suited particularly to the metathetic reactions of hydrocarbons.
- It is suggested here that metathetic continua may not be amenable to investigation as relative class concepts.

metathetical

adjective mɛtəˈθɛtɪk(ə)l

Now it is certainly possible to rig up such a metathetical reaction where the ions change partners and both precipitate!
Example sentencesExamples
- The metathetical process to generate isocyanates allows also for facile formation of sterically demanding aryl isocyanide, by a deoxygenation route.
- Methanol extraction of the as-synthesized nanocrystals from the metathetical reaction of GaCl3 with (Na / K) 3As resulted in surface derivatization of the nanoparticles in which methanol capped GaAs quantum dots were obtained.
- Furthermore, we have found that the throughput for the process is improved when an ammonium salt is used for the metathetical second step of the process.
- Both thermal (in solid state) and metathetical polymerization (using WCl6 / tetramethyltin catalyst and chlorobenzene solvent) of bisnadimides was carried out.

Origin

Late 16th century: from Greek, from metatithenai 'transpose, change the position of'.
