† menachinn.

Forms: 1800s menacchine, 1800s–1900s menachin.

Origin: Apparently from a proper name, combined with an English element. Etymons: proper name Menachan , Manaccan , -ine suffix⁵.

Etymology: Apparently < menach- (in Menachan, variant of the place name Manaccan: see menaccanite n.) + -ine suffix⁵. Gregor's coinage (apparently in German; compare quot. 1818) has not been traced; compare menaccanite n. and discussion at that entry.

Chemistry. Obsolete.

An element whose presence in the mineral menaccanite was deduced by W. Gregor, later identified with titanium.
