“There would be different types of silence, and speakers of this language would immediately know which type they were in. There would be a type of silence for when you weren’t saying anything and another, different type for when you weren’t saying something. There would be a third type, for when you didn’t know the word that captured the feeling you were having, a fourth type for when you knew the word but didn’t want to say it, since in saying it you would clip the feeling’s wings, and a fifth type, the rarest and most quiet, for when you weren’t saying something but the person you were talking to already knew what it was.”
