Brit.

/manˈɡanɪk/,

/maŋˈɡanɪk/, U.S.

/mænˈɡænɪk/,

/mæŋˈɡænɪk/

Forms: 1700s munganic (irregular), 1800s– manganic.

Origin: A borrowing from French. Etymon: French manganique.

Etymology: < French manganique (1789) < mangan- (in manganèse manganese n.) + -ique -ic suffix 1b. Compare manganesic adj., and note s.v. mangani- comb. form.

Chemistry.

Of or containing manganese in one of its higher valencies, esp. in the trivalent state; manganic acid n. H₂MnO₄, the hypothetical parent acid of the manganates.
