arseniousadj.

Brit.

/ɑːˈsiːnɪəs/, U.S.

/ɑrˈsiniəs/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: arsenic n., -ious suffix.

Etymology: < arsen- (in arsenic n.) + -ious suffix, after French arsénieux (1792 in the passage translated in quot. 1795). Compare earlier arsenic adj., arsenicated adj., and later arsenous adj.

Chemistry.

Of, relating to, or containing arsenic; spec. forming names of compounds and salts in which the element has an oxidation state of +3. Cf. arsenic adj.Recorded earliest in arsenious acid n. at Compounds.
