This book is aimed at children in the early school years. Theoretically, it covers the material prescribed by the current Curriculum of the Ministry of Education for the 1st and 2nd grades of primary school, concerning Verbs, Nouns, and Adjectives. The approach to these grammatical phenomena is made by the child through research and observation. What the child discovers on their own will become the rule, which they are then called upon to learn and remember forever. Mastery and assimilation are achieved with ease and comfort through a wide variety of suitable exercises that follow at the end of each lesson.
