The spelling of the word "Hoful" may seem unusual, but it follows the principles of the International Phonetic Alphabet (IPA). The /h/ represents the voiceless glottal fricative, while the /o/ represents the mid-back rounded vowel. The /f/ corresponds to the voiceless labiodental fricative, and the /u/ represents the high back rounded vowel. Finally, the /l/ is the voiced alveolar lateral approximant. Together, these sounds create the pronunciation of "Hoful." While it may take some practice, understanding IPA can help with accurate spelling and pronunciation of words.
