In a way that involves the rearrangement of sounds or letters in a word.
The word was pronounced metathetically, changing its original sound structure.
Metathetically → It is formed from "meta-" (meaning change or beyond) and "thesis" (from Greek "thesis", meaning placing or position) and the suffix "-ically" (meaning in a manner). The word refers to something that is related to a change in position or a change in the way something is placed or understood.
Think of 'meta-' meaning change and 'thesis' meaning position — together they suggest a change in how something is positioned or understood.
