abusive behaviour

Is there a verse in the Quran forbidding vulgar language and abusive behaviour?
I was searching the perfect word of Allah but I couldn’t find one.
The Quran is a thick book. I’m looking for a verse prohibiting it directly, not something remotely related that “can be interpreted” as a prohibition.
Yes brother, there is a very clear verse.
O ye who believe! let not one people deride another people, haply they may be better than they, nor let one group of women deride other women, haply they may be better than they. And do not defame your people nor call one another by nick-names. It is an evil thing to be called by bad name after having believed; and those who repent not, such are the wrongdoers. (49:11
Hope that helps. Allah bless you.
love for all, hatred for none
