niobiten.

Brit.

/ˈnʌɪə(ʊ)bʌɪt/,

/nʌɪˈəʊbʌɪt/, U.S.

/ˈnaɪəˌbaɪt/,

/naɪˈoʊˌbaɪt/

Origin: Of multiple origins. Partly a borrowing from German. Partly formed within English, by derivation. Etymons: German Niobit ; niobium n., -ite suffix¹.

Etymology: In sense 1 < German Niobit (W. Haidinger in Handb. der bestimmenden Mineral. (1845) 549) < Niob- (in Niobium niobium n.) + -it -ite suffix¹ (compare sense 2b s.v.). In sense 2 independently < niob- (in niobium n.) + -ite suffix¹ (compare sense 4b s.v.). N.E.D. (1907) gives only the pronunciation (nəi·ŏbəit) /ˈnaɪəbaɪt/.
