The spelling of the word "tzazo" can be explained using the International Phonetic Alphabet (IPA). The first two letters, "tz", represent a voiceless alveolar sibilant affricate. This sound is made by briefly stopping the airflow at the alveolar ridge, then releasing it with a hissing sound. The next letter, "a", represents an open central vowel, pronounced with the tongue relaxed and the mouth slightly open. The final two letters, "zo", represent a voiced alveolar fricative followed by an open back rounded vowel.
