Notes

The kosoado system — KO / SO / A / DO
Japanese has a four-way distance system. KO = near speaker, SO = near listener, A = far from both, DO = question. L02 covers the first two rows: pronouns (これ／それ／あれ／どれ — stand alone) and adjectives (この／その／あの／どの — attach to a noun). L03 will add the location row (ここ／そこ／あそこ／どこ).
これ vs この — the load-bearing distinction
これ STANDS ALONE — it IS the thing. → これ は ほん です。 ("This is a book.") この MUST ATTACH to a noun — it MODIFIES the noun. → この ほん は… ("This book is…") You cannot say この は ほん です — ungrammatical. You also cannot say これ ほん です — also ungrammatical (missing は). Rule: if no noun follows, use これ／それ／あれ. If a noun follows, use この／その／あの.
の — three jobs in one particle
の joins two nouns [N1] の [N2]. The relationship depends on context. (1) Possessive: ミラーさん の かばん → Mr. Miller’s bag. (2) Origin / kind-of: にほんご の せんせい → a Japanese-language teacher. くるま の ざっし → a car magazine. (3) Standalone (implied noun): この かさ は わたし の です。 → "This umbrella is mine." — the second かさ is dropped because everyone knows what we’re talking about. Order rule: [modifier] の [head]. The noun on the RIGHT is the main one; the noun on the LEFT describes it.
なん vs なに — phonological split
Both mean "what." The split is about what comes AFTER. なん before です, で, or any /d/, /t/, /n/ sound: なん です か, なん の ほん. なに before everything else: なに を たべます か (covered L06). In L02 everything is なん because the next sound is always です or の.
だれ vs どなた — politeness split
Both mean "who." The split is about register. だれ — neutral. Use with peers, classmates, friends. どなた — polite. Use with strangers, customers, elders, or when the situation calls for respect. In the Santos/Yamada Kaiwa, Yamada uses どなた because he doesn’t yet know who is at the door.
ちがいます — the polite "wrong" word
When the answer is "no," you have two options. いいえ、わたし の じゃ ありません。 — formal structural denial, mirrors the question. いいえ、ちがいます。 — softer "no, that’s not right." Use this when the assumption itself was wrong. Both are polite. ちがいます is also for gentle correction — it doesn’t accuse, it just says the picture isn’t right.
Standalone-の reflex — drop the second noun
When the question already named the noun, the natural answer drops it on repeat. Q: この かさ は だれ の かさ です か。 → A: わたし の です。 (NOT わたし の かさ です。) Repeat the second noun ONLY when introducing it for the first time. This ellipsis is what makes the answer feel natural to a native ear.
Never use これ for a person
これ is for THINGS only — using it for a person sounds dismissive. To introduce a person politely, use こちら (L01). For a third-party person, use この かた (polite) or この ひと (neutral). L01: こちら は ミラーさん です。 → "This is Mr. Miller." L02: これ は ほん です。 → "This is a book." Crossing the streams (これ for a person) breaks register.
