The spelling of the word "kwong" can be explained using the International Phonetic Alphabet (IPA) transcription system. The first sound, "kw", represents a voiceless labialized velar stop. This means the sound is produced by stopping the airflow at the back of the mouth and then releasing it while rounding the lips. The second sound, "ong", represents a nasal mid-back rounded vowel. This means the sound is produced by a continuous airflow through the nasal cavity while rounding the lips and placing the tongue in the back of the mouth. Together, these sounds make up the unique spelling of "kwong."
