This in-depth analysis helps us to appreciate the richness and complexity of grammar, and also enables us to make more informed decisions when it comes to using language.

In conclusion, a good understanding of grammar as a whole and a deep analysis within grammars are essential for anyone who wishes to master a language. It not only helps us to communicate better but also enriches our understanding and appreciation of the language and its culture.
