16.91

非愛麁惡語者，亦具四緣：一、染污心。二、發非愛語，毀呰於他。三者、解義。四者、不誤。名麁惡語。染心語三字，並從初句流來，應言：染心非愛語，說名麁惡語。解義不誤亦從前來。

Regarding "disagreeable harsh speech," it also requires four conditions: first, a defiled mind; second, uttering disagreeable words that insult another; third, [the other] understanding the meaning; fourth, not being mistaken. This is called harsh speech. The three characters "defiled-mind speech" are all carried over from the first line; it should say: "disagreeable speech with a defiled mind is named harsh speech." Understanding the meaning and not being mistaken are also carried over from before.
