At Wheelock's you learn Latin step by step, having as your teacher, an attentive master, who knows the best path to the learning of the language of Horace, Cicero and Virgil and others (sure, they and many others are all there, with texts progressively adapted according to the level of proficiency of the student). Latin sentences to be translated into English and the other way around abound, with all the necessary vocabulary listed before the exercises. If more is needed, the student is helped by a very good glossary at the end of the book, where all the words are listed in alphabetical order and according to Latin use of the nominative and genitive cases in the case of nouns and adjectives, and, in the case of verbs, with verbs listed in alphabetical order, in the Latin way, e.g., (amo, as, are, atum). Keys to the exercises are also presented in the end of the book, thus facilitating your doing of your Latin homework workload.
The book begins with the conjugation of the verbs in the first regular conjugation and proceeds till the 4th regular conjugation and then the student is presented to the passive forms of the regular conjugations, the irregular ones, the semi-deponents and , finally, the deponents verbs, a very Latinian form of conjugation. Along the way, he/she is presented to the important concept of declensions, used in the so-called synthetic languages (Greek, Russian, German, for instance) being gradually introduced to the "conjugations" of nouns, adjectives and numerals in Latin. All this, as I said, nice and easily, learning a lot of useful things along the way.
I could imagine of no better Latin grammar for the student of English nowadays and I hope you enjoy its reading and exercises as much as I did. Valete!!
