語源
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.

-
Ich wies hierauf diesem Foßile, als einer eigenen Gattung, sogleich eine Stelle in dem Kalkgeschlechte an; und ertheilte ihm, – weil es bisher alle Mineralogen in seiner Bestimmung irre geführt hatte, – den Namen Apatit, den ich von dem griechischen Worte απατάω (decipio) bildete, und welcher so viel as Trügling sagt.
- I then immediately assigned to this fossil [i.e., material obtained from underground], as a separate type, a place in the lime lineage; and conferred on it, — because it had previously led astray all mineralogists in its classification — the name apatite, which I formed from the Greek word απατάω (I deceive), and which says as much as [the word] deceiver.

Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite, chlorapatite and bromapatite, named for high concentrations of OH−, F−, Cl− or Br− ions, respectively, in the crystal. The formula of the admixture of the four most common endmembers is written as Ca10(PO4)6(OH, F, Cl, Br)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6(F)2, Ca10(PO4)6(Cl)2 and Ca10(PO4)6(Br)2.
