The Sanskrit word 'duṣṭa' or 'dhoṣita' (दोषित) means 'corrupt', 'polluted', 'impure', 'defiled', or 'tainted'. It refers to something that has been contaminated or morally degraded. While related to concepts of impurity, 'polluted' is the most accurate translation among the options. This is different from 'miśra' (mixed) or 'śatru' (enemy).
