 Kashrut (also kashruth or kashrus, כַּשְׁרוּת) is the set of Jewish religious dietary laws. Food that may be consumed according to halakha (Jewish law) is termed kosher / ˈkoʊʃər / in English, from the Ashkenazi pronunciation of the Hebrew term kashér (כָּשֵׁר), meaning "fit" (in this context, fit for consumption).
