Learning a language is usually a two step process. First you learn basic grammar and vocabulary. Then you move on to learning the more subtle nuances and exceptions and slang and idioms.
In Gengo Girls we’re only going to cover the most basic of preposition grammar. It will be enough to get you started but won’t really explain everything.
To go further you’re going to need an intermediate book like Essential Japanese Grammar. This book lists several dozen common-but-hard-to-fully-understand words and clearly explains exactly how they should and shouldn’t be used. For example, it has seven whole pages devoted to the different ways to use the preposition “ni”.
You’re probably not ready for a book like that just yet, but you might want to look it up after you’ve been studying for a year or two and have finished mastering the basics.
