This forty minute video by YouTuber Misa from Japanese Ammo might be one of the only resources titled “ultimate” and “the only lesson you need” that I actually believe. Misa breaks down the particles は and が and explains the differences in depth with multiple examples and on-screen text and translations.
は and が can be a major struggle for English speakers learning Japanese. If you don’t learn the nuances right away, you can spend a long time confusing the two. And misusing them will make you sound non-native 100% of the time. But Misa’s video trumps all other resources that we’ve found. It’s like taking Jay Rubin’s previously #1 explanation from Making Sense of Japanese and putting a younger, more approachable/conversational spin on it.[Annotation by Kristen Dexter | Tofugu]
