The main difference between a regular grammar and a context-free grammar lies in their complexity and the types of languages they can generate.

1. Regular Grammar:
- Regular grammars are simpler and less powerful. They can only generate regular languages.
- They have rules of the form A - aB or A - a, where A and B are non-terminal symbols and a is a terminal symbol.
- They are used in search engines and text editors for simple search and replace functions.

2. Context-Free Grammar:
- Context-free grammars are more complex and powerful. They can generate a larger set of languages, including all regular languages and some non-regular languages.
- They have rules of the form A - γ, where A is a non-terminal symbol and γ is a string of terminal and/or non-terminal symbols.
- They are used in programming languages and compilers to parse expressions and statements.

In summary, the main difference is that context-free grammars can generate a larger set of languages and handle more complex structures than regular grammars.
