Definition

1. Adjective:
   • Not conforming to dietary laws: Specifically used in Jewish dietary law (kashrut) to describe food that is not kosher, meaning it is forbidden to be eaten according to religious regulations.

Usage

• The adjective "tref" is used exclusively in the context of Jewish religious observance to classify food items. It is the direct opposite of "kosher."
• It is typically used attributively (before a noun) or predicatively (after a linking verb like "is").
• Important Note: "Tref" is a term from Yiddish, derived from Hebrew. Its use is specific to discussions of kashrut.

Examples

• Attributive use:
  • They discovered the meat was tref because it was not slaughtered according to ritual practice.
  • The restaurant was accused of serving tref dishes alongside kosher ones.
• Predicative use:
  • According to our rabbi, this cheese is tref.
  • If the animal has a certain defect, it is considered tref.

Advanced Usage

• The concept of "tref" extends beyond just the type of animal or food. It can refer to the method of slaughter (), the mixing of meat and dairy, or the presence of specific forbidden parts or ingredients.
• "Trefa" is a related term, often used interchangeably as an adjective or as a noun to mean "non-kosher food."

Synonyms
