Polish grammar is much more complicated than in English, every noun in Polish has 7 different grammatical cases. Declension is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection, and that's what I'll try to teach you today. The names of 7 cases are :Nominative (mianownik) Genitive (dopełniacz) Dative (celownik) Accusative (biernik ) Instrumental ( narzędnik ) Locative miejscownik) Vocative (wołacz)Each has some helpful questions assigned to it, so you can reformulate noun in easier way. Some students, in order to remember the order of cases faster, invent concepts in which the first letters of consecutive words correspond to the first letters of each case, eg: Normally Gina Does An Incredible Liquorice Valuable. It doesn't have to make a perfect sense, actually brain learns abstraction more easily- just don't forget about the order![table in word uploaded] Note that although in the following cases the word takes on a different form, there is a part of it which does not change and thanks to it we are still aware that it is the same word. Teachers explain the subject matter and ending using the example of a woman who changes his outfit. Mother in a dressing gown, tracksuit, evening dress is still the same mother, clothes only inform us that, for example, mom just took a shower, ran or in a moment goes to a party. Therefore - mom is a topic, and clothes are endings selected to the circumstances.
