Step-by-step explanation:
The student's question focuses on codifying the grammar for a widely spoken language, specifically Spanish, which is spoken by about 400 million people across diverse regions.
The Spanish Royal Academy has taken on the monumental task of publishing a comprehensive collection of Spanish grammar rules, attempting to standardize and address the variations in pronunciation, vocabulary, and sentence structure inherent in such a globally dispersed language.
This new published work will update and replace the previous edition from 1931. With the importance of Spanish as a language within the United States and globally, given that it is the second-largest Spanish speaking country in the world and has historical Spanish settlements, understanding its standardized grammar is essential.
American linguistics recognizes the value and influence of Spanish, offering insights into the language's evolution and the history of its speakers.
