Let's face BIERNIK (Accusative)

          As you may already know, Polish people change the endings (suffixes) of all adjectives and nouns all the time and it's pretty hard to learn when to use which ending. But I will help you to understand it, to practise and to remember.

For example if someone's name is ADAM, I can say: To jest Adam. (This is Adam). But when I say: Chcę zatańczyć z Adamem (I want to dance with Adam), I change the ending of his name- I dont say any more: Adam, but Adamem. And again, when I say: Myślę o Adamie (I'm thinking about Adam), I change the ending for diffrent
one. So we have: Adam, Adamem, Adamie.. looks pretty confusing for now, doesnt it? But let me explain step by step.

Firstly, you should know we have 7 cases in Polish (cases are resposible for those endings changes):

Mianownik- Nominative (basic form, the one you find in dictionary)

Dopełniacz- Genitive

Celownik- Dative

Biernik- Accusative

Narzędnik- Instrumental

Miejscownik- Locative

Wołacz- Vocative

We use cases to change the endings of adjectives and nouns.

Today:

BIERNIK (ACCUSATIVE)

First of all, you should remember how to know which noun is masculine, which one is feminine and which one is neutral. It is very important if you want to learn cases! So most of the time feminine nouns finish with -a (e.g. kawa, woda, spódnica), neutral with -e or -o (e.g. piwo, dziecko, okno) and the rest of them are masculine. 

Now: 

When do we use the Accusative?

If you are going to use in the sentence one of the following words:

lubić (to like), mieć (to have), chcieć (to want), jeść (to eat), pić (to drink), woleć (prefer), proszę (please), kochać (to love), oglądać (to watch), czytać (to read)

 then the word/ words (noun OR adjective+noun) which is after one of those should has Accusative endings.

 So the first sentence is: Lubię kawę (I like coffee). 

I have explained you that the word which follows the verb 'lubić' should has Accusative endings. The coffee is 'kawa' in Polish, but saying: "Lubię kawa." is not correct. I need to use Accusative, that is why I will say: "Lubię kawę."

Now you should learn what are Accusative endings for masculine, feminine and neutral adjectives and nouns.

We divide masculine nouns for animate and inanimate. To say very generally animate ones are: people, animals, fruit, vegetables.

Ok, let's try. How would you say in Polish: 

'I love watching TV'?

As you know, the verb 'to watch' should be followed by Accusative, so TV will have the Accusative ending.

TV is 'telewizja' in Polish. Is the word 'telewizja' masculine, feminine or neutral? It is feminine, because it ends with 'a'. So have a look at endings in the picture above (telewizja is a noun, feminine), so we can say:

Kocham oglądać telewizję. 

The second example:

I have a tall brother.

I have- mam

a tall brother- wysoki brat

Which words should have Accusative ending? Of course: a tall brother as they follow the word 'I have'('mam') which works with Accusative.

Is 'brother' masculine, feminine or neutral noun? Masculine. Ok, animate or inanimate? Animate. So:

Mam wysokiego brata.
