The word "adonite" (/ˈædənaɪt/) is a rare mineral consisting of phosphate of lead and copper. The spelling of this word is derived from the Greek word "adonis", which was the name of a mythical Greek god associated with fertility and rebirth. The ending "-ite" indicates that it is a mineral or rock, and thus follows common naming conventions in geology. Hence, the word "adonite" is an amalgamation of its Greek-originated root and the mineral nomenclature ending.
