Schnapps is a type of distilled alcoholic beverage. The English word schnapps is derived from the German Schnaps (plural, Schnäpse), which can refer to any strong alcoholic drink but particularly those containing at least 32% ABV (64 proof). American schnapps, however, are liqueurs.
The German word is pronounced [ʃnaps] ( listen); in English it is /ˈʃnɑːps/ or /ˈʃnæps/.
Schnaps is a Low German noun that means swallow; it has been documented in its High German meaning since before the 18th century.
