Okay, so let's say you want to understand a tricky sentence like "The cat chases the mouse". That sentence has a subject (the cat), a verb (chases), and an object (the mouse). These parts of speech are called "syntax", and people like Noam Chomsky study them to understand how language works.
Now, imagine a more complex sentence like "After running through the field, the dog chased the tennis ball that was thrown by the owner". That's a lot of information to process! Chomsky's theory suggests that we have an innate ability to understand and generate complex language, almost as if our brains were pre-wired for it. He called this "universal grammar".
To understand Chomsky's decoding theory, you have to know a little bit about language acquisition. As babies, we start by babbling and making simple sounds. Then, we gradually learn more and more complex grammar rules without being explicitly taught. Chomsky believed that all humans have the same basic building blocks for language, regardless of the specific language we speak.
So what does this mean for decoding language? Essentially, Chomsky argued that we can understand complex sentences because we have an innate understanding of the underlying structure. For example, we know that "the dog chased the ball" is a complete sentence because it has a subject (the dog) and a verb (chased). We also know that "that was thrown by the owner" is a subordinate clause because it provides additional information about the ball.
Chomsky's theory suggests that our brains are hardwired to understand these patterns, which makes it easier for us to decode complex language. Of course, not everyone agrees with Chomsky's ideas, and there are many different approaches to studying language. But hopefully that gives you a basic idea of what decoding Chomsky means!
