Context free language
Okay, let's imagine that you and your friends have a secret language that only you can understand. However, there are some rules that you all have to follow so that the language makes sense. For example, if you want to say that you're hungry, you might say "I want food."
A context-free language is kind of like that secret language you and your friends have. It's a set of rules that we use to describe how words can be put together to make sense. These rules are called "grammar rules."
For example, if we have the words "cat" and "dog," we can use a grammar rule to put them together and say "The cat chased the dog." The grammar rule says that we have to start with "The" and end with ".", and we have to put "cat" and "dog" in the right places in between.
Context-Free languages can also have more complex grammar rules that allow us to create more complex sentences. For example, we could have a grammar rule that says "If we have a noun phrase followed by a verb phrase, we can put them together to make a sentence." And then we could use other grammar rules to define what a noun phrase and a verb phrase are.
In summary, a context-free language is a set of rules (grammar rules) that describe how words can be put together to make sense. Like how you and your friends have a secret language, a context-free language follows rules to make sure that sentences make sense.
