José Maria Relvas developed his grammar specifically to cater to various levels of the school system, from primary education to the first cycles of "Liceal" (high school) studies. Its primary strength lies in its didactic simplicity, often incorporating "Exercícios de Aplicação" (application exercises) to reinforce theoretical concepts. Key features of this grammar include:

: Because it is considered a "Livro Único" (standardized textbook) from a specific historical era, it is a common item in antiquarian bookstores like Alfarrabista .

: Specific editions tailored for the 1st, 2nd, and 3rd classes of the old Lyceum system.
