Okay kiddo, so you know how we have different languages like English, Spanish, and Chinese? Well, there is a fancy word we use called "bromide" to describe a type of language that uses really predictable and boring phrases. It's like if someone always says the same thing over and over again, it can get pretty boring and not very interesting to listen to.
For example, if someone says "how are you" every time they talk to you, instead of mixing it up and saying things like "what have you been up to" or "how was your day," it can start to feel like they're not really paying attention or putting effort into their conversation.
So, in short, bromide language means using the same old phrases over and over again instead of being creative and interesting with your words.
