The word "hazans" is spelled with a "z" instead of an "s" due to its pronunciation. The phonetic transcription of the word is /ˈhæzənz/, with a voiced "z" sound in the middle of the word, followed by an "s" sound. This pronunciation is derived from the Arabic word "hassan," which refers to a leader or chief of a tribe. In English, "hazans" can be used to refer to Jewish cantors, also known as hazzans or chazans.
