Tell that to the person who came up with the word "Nazja", or names for locations such as Nazjatar.
Also you are not pointing out anything obvious. It's even pronounced differently. The "naz" preffix taken from the word Nazja is pronounced "na·z" and the "naz" from the word you are probably reffering to is being pronounced as "naat·s". Bye.
