The spelling of the word "chinn" is often mistaken due to its phonetic complexity. In IPA phonetic transcription, "chinn" is spelled as /tʃɪn/. The first two letters "ch" represents the voiceless postalveolar affricate, which is pronounced by releasing air through the narrow space between the tongue and the palate. The following letter "i" represents the short vowel sound, while the last letter "n" represents the nasal consonant, pronounced by vibrating the vocal cords as air passes through the nose.
