Generation

A context-free grammar is a set of rules for generating valid strings in a language, like defining what makes a proper sentence. Each rule says you can replace a symbol (like "Sentence") with a sequence of other symbols (like "Noun Verb Noun"), and you keep applying these replacements until you have only terminal symbols (actual words or characters). The key feature is that each replacement rule works independently—you can replace a symbol regardless of what surrounds it, which is why it's "context-free." These grammars are powerful enough to describe most programming language syntax and many aspects of natural languages.
