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 but 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
