Deriving the cases — start here Accusative = arrow, dative = dot. The cases are derived from a single picture; includes how they map to the Finnish cases and the few real exceptions. Prepositions All prepositions by case, two-way prepositions (wo/wohin), verb pairs, time expressions and contracted forms. Verbs and their prepositions About 130 verbs and adjectives with a fixed preposition and case; meaning pairs and da-/wo- compounds. Articles Articles and pronouns in all cases — and what really changes in them. Gender der, die or das from the ending of the word (-ung, -chen, -um …) and from its meaning, and how reliable each rule is. Plural The plural ending (-n, -e, -er, -s, no ending) from the gender and the final letters, umlaut, the dative -n and the closed lists. Body parts A diagram of the human body with each part in the colour of its article, plus the words in tables — and the rules that apply here too. Pronunciation (A1) Vowel length, ei/eu/ie, ch, s/z/w and stress — the points where a Finnish speaker slips. Verbs: present, imperative, perfect (A1) Regular endings, vowel change (e→i, a→ä), sein/haben, separable and modal verbs, the imperative and a first look at the perfect. Word order, questions, negation (A1) Verb second, yes/no and W-questions, nicht or kein and where nicht goes. Nominative, accusative, dative (A1) The three A1 cases on articles and pronouns, and the possessives mein, dein, sein, ihr. Numbers and time (A1) 0–100 and beyond, clock times with halb and Viertel, weekdays, months, am/um/im. Adjectives: endings and comparison (A2) der alte, ein alter, kalter: the three ending tables and two rules; älter, am ältesten; als and wie.
