Latin for Beginners by D'Ooge, Benjamin (Hardcover)

Total 348 pages + the key for exercises.

One of the classic texts of Latin language education. It is a quite popular grammar-heavy approach textbook that many students like.

D'Ooge designed this beginners grammar to prepare the student for reading Caesar. The grammar consists of seventy-nine lessons divided into three parts. The lessons are very well structured, gradually introducing new vocabulary and grammar. There is plenty of acummulative knowledge, meaning that you don´t forget what you learnt in previous lessons. Things keep popping back to refresh your memory.
