Hi everybody! I know the nominative is used for the subject of a sentence and accusative is used for the direct object of a sentence, but I don´t know when use nominative and when use accusative. For example, Мы видим море (we see the sea), is accusative sentence, but it could be a nominative if I used for the subject and not for the object. I mean nouns in the nominative answer such questions as What? and Who?, if I make a question: WHO see the sea? We see the sea, it´s nominative. The nouns in the accusative answer such questions as Whom? and What?, if I make a question: WHAT do we see? We see the sea´, it´s accusative.
