Lashon Hara

The Hebrew term lashon hara (or loshon hora) (Hebrew לשון הרע; "evil tongue") is the halakhic term for derogatory speech about another person. Lashon hara differs from defamation in that its focus is on the use of true speech for a wrongful purpose, rather than falsehood and harm arising. By contrast, hotzaat shem ra ("spreading a bad name"), also called hotzaat diba, consists of untrue remarks, and is best translated as "slander" or "defamation". Hotzaat shem ra is worse, and consequentially a graver sin, than lashon hara.

The act of gossiping is called rechilut, and is also forbidden by Jewish law.

Speech is considered to be lashon hara if it says something negative about a person or party, is not previously known to the public, is not seriously intended to correct or improve a negative situation, and is true. Statements that fit this description are considered to be lashon hara, regardless of the method of communication that is used, whether it is through face-to-face conversation, a letter, telephone, or email.

The sin of lashon hara is considered to be a very serious sin in the Jewish tradition.
