 A person or object which contracts "ṭumah" is said to be "ṭamé" (טמא Hebrew adjective, "ritually impure"), and thereby unsuited for certain holy activities and uses ("kedushah" in Hebrew) until undergoing predefined purification actions that usually include the elapse of a specified time-period.The contrasting Hebrew noun "ṭaharah" () describes a state of ritual purity that qualifies the "ṭahor" (; ritually pure person or object) to be used for "kedushah".The most common method of achieving "ṭaharah" is by the person or object being immersed in a "mikveh" (ritual bath).
