Add Wortschatz & Grammatik A1 Abschnitt N-Q, completing the book

- N Fragen: W-Fragen, ja/nein/doch (reinforces Menschen L1, L3)
- O Satzstellung: V2 rule, Satzklammer, Nominativ/Akkusativ/Dativ
  complements (reinforces L1/L4/L7/L9/L11, extends Dativ work)
- P Konjunktionen: denn/aber/oder (new, not in Menschen A1.1)
- Q Zahlen: cardinal number review, ordinal numbers and date-writing
  (new beyond L4/L8's cardinal numbers and clock times)

Wortschatz & Grammatik A1 is now fully processed end to end
(Abschnitt A-Q, 103 sub-exercises). INDEX.md summarizes which grammar
points across Teil 2 go beyond Menschen A1.1's scope.

+# Wortschatz & Grammatik A1 — Abschnitt O: Satzstellung
+
+Seiten 98–100 (Teil 2 Grammatik) · Lösungen S. 114–115 · Übungen O1–O4
+
+## Overview
+
+- Skill focus: Grammatik (V2 word order, sentence building from
+  fragments/word clouds, identifying Nominativ/Akkusativ, Dativ
+  complement forms)
+- Topic: building grammatically correct sentences with the verb in
+  position II, sentence construction from scrambled word groups,
+  identifying subject/object in a text, Dativ object practice in
+  everyday dialogues
+- Relates to *Menschen* Lektion(en): **L1, L4, L7, L9, L11** (V2 word
+  order and the Satzklammer — this section is a systematic, explicit
+  statement of the rule that's been used implicitly throughout Menschen
+  A1.1: verb bracket with modal/Perfekt in L7/L11). **O4's Dativ
+  complement forms** extend the Dativ pronoun work from Abschnitt L —
+  still **new beyond Menschen A1.1**.
+
+## Grammar covered
+
+### O1: Verb in Position II — explicit rule, ties together Menschen L1–L12
+**Tipp**: Das Verb steht immer auf **Position II**! (Ausnahmen:
+Satzfrage [verb-first yes/no questions], Imperativ.) Das Subjekt steht
+immer auf Position I oder kommt gleich nach dem Verb.
+
+This is the first place in either book where the V2 rule is stated as an
+explicit, standalone principle — Menschen A1.1 uses it constantly but
+never names it this directly. Good "aha" moment content: connecting
+dots the student has already been using intuitively.
+
+### O2: Satzklammer (verb bracket) — reinforces Menschen L7/L11
+Sentence-building from word clouds, where the two parts of a split verb
+(modal+infinitive, haben/sein+Partizip II, or separable-prefix pairs)
+must land in the correct bracket positions (position II and the very
+end of the clause) — direct continuation of the Satzklammer concept from
+Menschen L7 (modal verbs) and L11 (Perfekt).
+
+### O3: Nominativ- und Akkusativergänzung — identifying subject/object
+A connected short story (Jörg sucht seine Brille) where the task is to
+mark which noun phrase is the **Nominativergänzung** (subject) and which
+is the **Akkusativergänzung** (direct object) in each sentence — a
+close-reading/grammar-awareness exercise rather than a production one.
+
+### O4: Dativergänzung — extends Abschnitt L's Dativ pronoun work
+Fill in the correctly declined Dativ form (pronoun or full noun phrase)
+for verbs/expressions that govern the Dativ: gefallen, passen, stehen
+(clothing), gratulieren, gehören, leid tun, danken, gehen (es geht mir
+gut). Still **new grammar beyond Menschen A1.1**.
+
+## Exercise summary
+
+1. **O1 Eine Ferienwoche** — build 12 full sentences from note-fragments
+   about Vera's vacation plans, correct V2 word order.
+2. **O2 Wort-Wolken** — assemble 7 sentences from scrambled "word cloud"
+   fragments, placing Satzklammer parts correctly.
+3. **O3 Wo ist sie nur?** — read a short story and mark the Nominativ-
+   and Akkusativergänzung in each of 9 sentences.
+4. **O4 Alltägliches** — fill in the correct Dativ form (pronoun or
+   noun) in 5 everyday dialogues.
+
+## Answer key highlights
+
+- O1: steht Vera um 8 Uhr 30 auf; geht oft ins Schwimmbad; geht sie ins
+  Theater; trifft Ella und Rudi; besucht die Großeltern in Bamberg;
+  joggt sie; kauft neue Schuhe; geht viel spazieren; geht sie ins Kino;
+  räumt den Keller auf; fährt sie an den Chiemsee; lädt sie Tante Tilla
+  ein.
+- O2: "Klara hat ihre Hausaufgaben nicht gemacht." "Ich habe das Wort
+  nicht verstanden." "Udo möchte eine Party machen." "Tina kann heute
+  nicht kommen." "Am Wochenende haben die Jungen Fußball gespielt." "Am
+  Freitag will ich dich zu meiner Geburtstagsparty einladen." "Kannst du
+  heute Nachmittag einkaufen?"
+- O3: Nominativergänzung/Akkusativergänzung pairs per sentence — e.g.
+  1. Jörg (Nom.) / seine Brille (Akk.); 2. Er (Nom.) / seinen Sohn
+  (Akk.), meine Brille (Akk., in the quoted question); full mapping for
+  all 9 sentences is in the source PDF at p. 114–115 if needed.
+- O4: dir; mir; mir / Kindern; den Eltern / mir; Ihnen; mir; Ihnen /
+  deiner Mutter / Ihren Eltern; ihnen.
+
+## Notes / gotchas
+
+- **O1's Tipp box is worth surfacing as a standing rule** whenever word
+  order questions come up — it names explicitly what Menschen A1.1
+  teaches only by repeated example (verb always in position II, subject
+  in position I or right after the verb).
+- **O3 is a "grammar awareness" exercise, not production practice** —
+  useful for a student who can already form correct sentences but
+  struggles to explain *why* they're correct (e.g. for exam prep or
+  self-correction skills).
+- **O4 continues the Dativ theme from Abschnitt L** — by this point in
+  the book the student has seen Dativ pronouns (L1), Dativ prepositions
+  (M4), and now Dativ verb complements (O4). Worth treating these three
+  as one connected grammar arc when reviewing, even though they're
+  scattered across different Abschnitte.
