The spelling of the word "zhoon" may seem unusual to many readers. However, it is actually a phonetic spelling of the Mandarin word "zhong" which means "clock". In IPA (International Phonetic Alphabet), the pronunciation of "zh" is /ʒ/, like the sound of the "s" in "measure". Thus, "zhong" is transcribed as /ʒoŋ/. The spelling of "zhoon" preserves the correct pronunciation of the word by using the English letter "z" to represent the /ʒ/ sound, followed by two "o"s to represent the vowel in the second syllable.
