Berenicium, pronounced /bɛrəˈnɪsiəm/, is a rarely used word in chemistry that refers to a hypothetical element with the atomic number 93. It is named after the constellation Berenice's Hair, and the -ium suffix denotes a metallic element. The word's spelling follows English phonetic rules, where the "e" after "r" makes the vowel preceding it pronounced with a schwa sound /ə/ instead of the long "e" sound. The letter "c" is pronounced with a soft "s" /s/ sound due to the following "i."
