fluaten.

Brit.

/ˈfluːeɪt/, U.S.

/ˈflueɪt/

Forms: 1700s–1800s fluat, 1700s– fluate.

Origin: Of multiple origins. Partly a borrowing from French. Apparently partly formed within English, by clupping or shortening. Etymons: French fluate ; fluosilicate n.

Etymology: In sense 1 < French †fluate ( L.-B. Guyton de Morveau Méthode de nomenclature chimique (1787) 114, the source translated in quot. 1788) < flu- (in fluor fluor n.¹) + -ate -ate suffix¹; compare post-classical Latin fluat- , fluas (1787 in Guyton de Morveau, or earlier), Spanish †fluato (1795 or earlier; 1788 or earlier as †fluate ), German †Fluat (1801 or earlier), all < French, and compare later fluoride n. In sense 2 apparently shortened < fluosilicate n., after French fluate (1887 or earlier); compare fluate v., fluatation n.In fluate of lime n. after French †fluate de chaux (1787 or earlier).

Now historical.

1. Chemistry. A salt made by combining fluoric (hydrofluoric) acid with a base; a fluoride. fluate of lime n. calcium fluoride, fluorite.
