Definition: "Unsilentious" is a phrase that describes someone who does not make any noise or sound, especially when they are not speaking. It can also be used to describe someone who is very quiet and doesn't talk much, like an uncommunicative person. For example: - "She was quite silent all evening," he said, "but I couldn't help but notice that she didn't speak." - "He seemed very quiet when we were in the park last weekend," Sarah said,
