for all you filipinos out there: what is the definition of metatesis? can u give me an example?

Answer 1

"metatesis" - spanish for metathesis, or the filipino equivalent for metathesis.
Metathesis is a sound change that alters the order of phonemes in a word. The most common instance of metathesis is the reversal of the order of two adjacent phonemes. Many languages have words that show this phenomenon, and some use it as a regular part of their grammar (e.g. Fur). The process of metathesis has altered the shape of many familiar words in the English language, too. Metathesis is one of the most common types of speech errors.

Metathesis in Tagalog (Filipino) - how a foreign word spelling is change to suit local pronunciation and spelling rules. This is similar to a process in slang derivation known as Metathesis, which is the switching of sounds within a word, either through inversion of syllables or by a re-arrangement of the letters. The two common ways that this is manifested in Filipino is either through syllable switching (as in astig from matigas or hard) or through full reversal of spelling (as in atab from bata or child)

Metathesis in English

In chemistry, metathesis refers to a reaction where parts of two reactants "switch places".
Metathesis is a bimolecular process involving the exchange of bonds between the two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations.[1] To illustrate, consider two chemical species, AB and CD, which react to give AD and CB:
AB + CD → AD + CB
