Eukolyte is a mineral with a unique spelling that may trip up even advanced spellers. The word is pronounced yoo-kuh-lahyt, with the stress placed on the second syllable. The spelling reflects the mineral's composition, which includes the Greek prefix eu-, meaning "good," and the root kolyte, which refers to a type of mineral composed of basic iron and magnesium silicate. This combination makes eukolyte a valuable mineral in industry and research, particularly in the production of ceramics and glass.
