Final answer:
A context-free grammar consists of a series of grammar rules that govern the syntax of a language, essential for compilers and interpreters.
Step-by-step explanation:
A context-free grammar consists of a series of grammar rules that determine how words in a language can be combined to produce sentences with correct syntax. These rules are crucial for programming language compilers and interpreters to understand and process the language constructs correctly. The process of developing these rules is often iterative and may employ methods like trial and error to refine the grammar. Moreover, the grammar represents a grammar set of rules that are crucial for conveying meaning in a structured and organized manner.
