Valleriite is a mineral that has a complex spelling but with a simple phonetic transcription. Its spelling is derived from its discoverer, Marcel Valléri. The word is pronounced as /væləraɪt/ with the symbol "æ" representing the sound in the word "cat", "ə" symbol representing the sound in the second syllable of "sofa", and "aɪ" representing the diphthong in "eye". Valleriite is found in nickel-copper sulfide deposits and has a dull metallic luster.
