This series of self-study language courses comprises grammar lessons, contextual conversation drills, relevant word lists, and graded exercises to allow the traveler an immediate grasp of a foreign language.
I'm sorry, but this is not a 'unique' guide to the language. It is good in delivering a working vocabulary, but the grammar sections are difficult to follow. Especially because the author has a penchant for inventing new names for grammatical items. They cannot possibly call the 'possessor case' by the traditional name 'genitive,' I suppose. And what the heck is a pre-present tense? Honestly. Let's take language courses back to the mid-twentieth century.
My final gripe: there are not enough examples. I suppose I'm supposed to jump right into a German precis with a basic vocabulary? Don't get this book. Get on Amazon or something and get an old-fashioned primer.
