Metathesis

Metathesis is a linguistic or chemical process where parts of words or molecules switch places. In language, it involves reversing the order of sounds or letters within words, like saying "aks" instead of "ask." In chemistry, it refers to reactions where parts of two compounds exchange partners, forming new substances. This process can occur naturally or be used intentionally to create variations—in language for speech patterns or poetic effects, and in chemistry for synthesizing new compounds efficiently.
