Steacyite is a rare mineral discovered in the zinc and lead deposits of the Keno Hill, Yukon Territory in Canada. The word is derived from the surname of a Canadian mineralogist, Frank W. Steacy. The correct pronunciation of steacyite is /ˈstiːsiˌaɪt/ (stee-see-ite), with the stress on the first syllable. The spelling of the word follows the standard English convention of matching a vowel sound with a corresponding letter, hence the use of the letter "e" after the letter "c" in the word.
