The Vietnamese word "róc rách" is a verb that means "to babble." It describes the sound of someone talking quickly and excitedly, often in a way that isn't very clear or coherent. This word is often used to refer to children or people who are happily chatting away.
In more advanced contexts, "róc rách" can also be metaphorically used to describe the flow of water, like a stream babbling over rocks, emphasizing the sound of water making its way over obstacles.
While "róc rách" primarily means to babble, it can also imply a sense of being carefree and joyful in one’s speech, suggesting a light-hearted atmosphere.
