The Plain Form is an essential grammar conjugation that's used in both writing and in speaking. It's useful not only in various grammar forms, but also as a regular speech style. However, it plays a unique role when used together with politeness levels, and I'll explain how that works throughout this course.
Remember that this course is completely free, and every week I'll post one new lesson until it's complete. The series will have 24 episodes in total. If you're a YouTube channel Member, you can even watch the rest of the episodes right now in advance.
