I’ve posted the second of the two lessons on expressions, Greetings and Other Expressions. You may want to start with the first, Names and Introductions. No grammar is necessary for these pages, but you’ll get the most out of them if you’ve read the Introduction to the Japanese Language up until Levels of Formality, which is now placed before the first grammar lesson.
So now, I’m going to start working on grammar to finish up the Intro.
