Mineralogist singular masculine, common name. -Is person who has studied and is an expert in minereologia, that is, at the same time, a branch of geology; i.e., the science that studies the minerals, as well as inorganic compounds on the planet. Etymologically the word mineralogist comes from two terms: one prerromance, Celtic, minus, which means [m] mine and the Greek suffix cult logos/Lodge, meaning 'word, Treaty, science, study, knowledge'.
