The four verbal misconducts and the four good verbal conducts.
Duccarita sutta - Misconducts
"Bhikkhus, these are the four misconducts by way of speech. What are the four? False speech, divisive speech, harsh speech, and idle chatter — these are the four misconducts by way of speech.
Bhikkhus, these are the four good conducts by way of speech. What are the four? Truthful speech, speech that is not divisive, gentle speech, and thoughtful speech — these are the four good conducts by way of speech."
