From international scientific vocabulary, from German Apatit (“apatite”). Apatit was coined by the German geologist Abraham Gottlob Werner (1749–1817), as follows: Ancient Greek ᾰ̓πᾰ́τη (ăpắtē, “deceit, fraud”) (as it is often mistaken for other minerals) + German -it (suffix forming nouns denoting minerals or rocks; cognate with English -ite); the German word was first used in a 1786 book. Regarding minerals that were named for being deceptive and thus confused with others, compare also fool's gold.
