'Language' in the Bible

Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].

Let all bitterness and wrath and anger and clamor [perpetual animosity, resentment, strife, fault-finding] and slander be put away from you, along with every kind of malice [all spitefulness, verbal abuse, malevolence].
