/ˌɑktəˈhidrɪk/

Forms: 1800s octohedric, 1800s– octahedric.

Origin: Formed within English, by derivation; perhaps modelled on a Latin lexical item, or perhaps modelled on a Italian lexical item, or perhaps modelled on a French lexical item. Etymons: octahedron n., -ic suffix.

Etymology: < octahedron n. + -ic suffix (compare -hedric comb. form), perhaps after post-classical Latin octahedricus (see octahedrical adj.), Italian ottaedrico (1681), or French octaédrique (1799). Compare earlier octahedrical adj., octahedral adj., octahedrous adj.On the form in octo- see discussion at octa- comb. form. N.E.D. (1902) gives the pronunciation of the second element as (-he·drik) /-ˈhɛdrɪk/.
