Japanese Genki 1 Grammar Made Clear

Source playlist: ToKini Andy - GENKI Grammar Made Clear, JLPT N5

This is a lookup note for the 12-video Genki 1 / JLPT N5 grammar playlist. It is organized around the question: “I remember this grammar point, but which lesson covered it?”

Transcript coverage

The lesson table of contents comes from the creator’s YouTube chapter markers for all 12 videos. I reviewed available YouTube captions where they were usable, but the captions are auto-generated and uneven. Treat the grammar index as a reliable chapter map; treat dialogue/practice summaries as paraphrased study aids, not extracted transcripts.

Mini Contrast Notes

から vs ので

Both can translate to “because,” but they feel different.

Form	Lesson	Feel
から	6 and 9	More direct reason/cause; often easy to start using first.
ので	12	Often softer or more explanatory; common when giving background or making a request sound less blunt.

は vs が

Particle	Main job in these lessons	Where
は	Marks the topic: “as for X…”	Lesson 1, Lesson 3
が	Marks the subject/newly identified thing; also appears with likes/dislikes	Lesson 8, Lesson 5

Subject が vs conjunction が

が use	Pattern	Meaning
Subject particle	N が ...	Marks the subject/newly identified item: “N is the one that…”
Desire/skill target marker	N が 好き / 嫌い / 上手 / 下手	Marks the thing liked/disliked or the skill area.
Conjunctive particle	S1 が、S2	Connects two clauses: “S1, but/however S2.”

Transcript check: I searched the cut Lesson 8 captions and the original live Lesson 8 captions for conjunction, connect, clause, however, although, and but near ga. In the live video around 1:40:20, Andy explicitly frames the section as subject-particle が and says he is only covering two subject-particle situations: emphasis and question words. So this playlist transcript does not appear to explain conjunction が, even though S1 が、S2 is a Genki Lesson 8 grammar point.

The many の uses in Genki 1

Use	Where
Noun-linking / possessive / descriptive の	Lesson 1, 16:47
Whose with だれの	Lesson 2, 24:25
Avoiding repeated nouns with の	Lesson 10, 17:34
Nominalizing a sentence with の	Lesson 8, 36:39
Explanatory のだ / んです	Lesson 12, 0:39
