However, you could use the English word "Mercury" or the scientific term "ʻO Mekuri," which is the Hawaiian pronunciation of "Mercury."

* Ka Hōkū ʻIʻo (The Metal Star) - highlighting its metallic composition.
Ultimately, the best way to say "mercury" in Hawaiian would depend on the context and what you want to emphasize.
