Inappropriate Speech

From Halachipedia

The Torah goes out of its way in a verbose way in order to use clean speed and to teach us a lesson in the importance of the purity of one's tongue. Therefore, a person shouldn't let a vile expression exit his mouth. [1]

Gravity of the Sin

  1. The Gemara states that even though everyone knows why a bride enters a wedding canopy, the one who fouls his mouth to speak about it will loose any good decree God had in store for him and that decree will be turned into a harsh decree.[2]

Using Positive Speech

  1. One should compliment a bride in a way that is nice and kind. [3]
  2. See the page about the Prohibition of Lying for details about lying for constructive purposes.
