Thus far we have focused on the statements which are derogatory in nature. The second category of loshon hara involves statements that could potentially cause harm to a person, be it physical, emotional or financial.
The Talmud teaches that gramma b’nizakin assur, it is forbidden to cause a person damage indirectly. Thus, any form of speech, even if not derogatory, but which may cause harm to someone, constitutes loshon hara and is forbidden.
