Brit.

/ˌniːə(ʊ)ˈtantəlʌɪt/, U.S.

/ˌnioʊˈtæn(t)lˌaɪt/

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: neo- comb. form, tantalite n.

Etymology: < neo- comb. form + tantalite n., after French néotantalite (P. Termier 1902, in Bull. de la Soc. Franç. de Minéral. 25 37).

Mineralogy.

A mineral found as yellow octahedra which was formerly thought to be dimorphous with tantalite but is now considered to be a variety of microlite.
