The correct spelling of the word "Hypasia" is /haɪˈpeɪziə/. The word does not follow the typical English phonetic rules, as the "y" and "s" sounds are combined through the "ia" ending. This pronunciation indicates that the "y" sound is pronounced as a vowel, similar to the "i" sound in "idea" or "eye". The "s" sound is also softened and elongated, sounding more like a "z". The use of IPA phonetic transcription allows for accurate pronunciation of words, helping improve communication and understanding.
