Supernatations is a word that refers to the process of settlement, where insoluble particles settle at the bottom of a liquid. The spelling of this word can be explained using IPA phonetic transcription as /ˌsuː.pər.næ.təˈʃʌnz/. The emphasis is on the second syllable, and the 't' in the third syllable is pronounced as a 't' instead of a 'sh' sound. The plural ending '-ions' is pronounced as /-ʌnz/ and adds an extra syllable to the pronunciation of the word.
