In Jewish law, ṭumah and ṭaharah) are the state of being ritually "impure" and "pure" respectively. The Hebrew noun ṭum'ah, meaning "impurity," describes a state of ritual impurity. A person or object which contracts ṭumah is said to be ṭamei (Hebrew adjective, "ritually impure"), and thereby unsuited for certain holy activities and utilisations (kedusha in Hebrew) until undergoing predefined purification actions that usually include the elapse of a specified time-period.
