The spelling of the word "HRIZ" may seem strange at first glance, but it is actually derived from the Greek word "χρυσός" (chrysos), meaning gold. The four letters in "HRIZ" represent the sounds /h/ (as in "he"), /r/ (as in "red"), /i/ (as in "bit"), and /z/ (as in "haze"). The use of the letter "z" rather than "s" may appear arbitrary, but it is actually a common convention in English words derived from Greek (e.g. "zodiac" from "zōidiakos").
