In linguistics, what does 'metathesis' involve?

Metathesis refers to the phenomenon where sounds in a word are rearranged or transposed. This process can often occur naturally in spoken language over time or in colloquial speech, leading to variations in the pronunciation of words. A classic example of metathesis is how some people might pronounce 'ask' as 'aks.'

This choice highlights the key aspect of metathesis, which is the movement or switching of sounds within the structure of a word. It showcases how phonetic changes can occur in language without altering the meaning of the original word, emphasizing an interesting aspect of linguistic change and sound patterns in speech.
