Pronunciation: [sˈɪmə͡ʊnə͡lˌa͡ɪt] (IPA) 
Simonellite is a rare mineral discovered in 1926 by mineralogist Simon Fraser. The word is pronounced [sɪˈmɒnəlaɪt] and is spelled as it sounds. The first syllable is pronounced as "si", followed by "mon" which is rhymed with "on". The "e" at the end of "ellite" is silent, and the final syllable is pronounced as "light". Simonellite is found in igneous rocks, and its formula is (Ca,Na)2(Be,Al)(SiO4)(F,OH)2.
Simonellite is a rare mineral that belongs to the halide group, and its chemical formula is (Zn,Fe)6(AsO4)2(OH)12·28H2O. It was first discovered in the Simon mine in the district of Hagen, Germany, hence its name. This mineral typically occurs as colorless to white crystals, but it can also be found in shades of green or yellow.
In terms of its physical properties, simonellite has a translucent to transparent appearance with a vitreous luster. It has a perfect cleavage on its {001} plane, and its hardness ranges from 3 to 4 on the Mohs scale, making it relatively soft. Simonellite often forms in oxidation zones of arsenic-bearing polymetallic ores, usually in association with other minerals such as scorodite, pharmacosiderite, and limonite.
From a geological perspective, simonellite is found in hydrothermal vein deposits and geodes. Its formation occurs through the interaction of oxidized zinc and iron minerals with arsenic-rich fluids, causing simonellite to precipitate out of solution.
In addition to its mineralogical significance, simonellite also has applications as an ore of zinc and as a potential source of arsenic. Due to its scarcity and limited availability, the mineral is mainly of interest to mineral collectors and researchers studying the geological processes responsible for its formation.
There is no specific information available regarding the etymology of the word "simonellite". It is possible that "simonellite" is a proper noun or a term coined in a specific context, and therefore its origins may not follow the usual etymological patterns seen in other words. Without further information, it is difficult to determine the etymology of this particular term.
