This next grammar lesson is another overview. Japanese Word Classes covers nouns, pronouns, verbs, all three classes of adjectives, and particles. Verbs and adjectives especially will get a more detailed treatment in later lessons, as will demonstratives (“ko-so-a-do” words) and counters, which I left out to keep things simple.
In other news, I’m thinking of moving the as-of-yet unreleased linguistics stuff to a separate series, much like the separate Kana Resources page. I might reorganize the Hiragana and The Japanese Sound System in order to separate out a more concise guide to pronunciation. This would make it easier for those starting from the beginning to get into the grammar and expressions stuff more quickly.
