The word "tucekite" is a rare and unusual term that might pose a challenge for some spelling bee contestants. It refers to a type of mineral, specifically a yellow or brownish-yellow iron-tungsten oxide. The word can be phonetically transcribed as /tju:ˈsiːkaɪt/, with the stress on the second syllable. The two Cs in the word are pronounced as the voiceless alveolar fricative sound /s/. Despite being a mouthful, "tucekite" is a fascinating word for those interested in geology or mineralogy.
