Сases All nominal parts of speech (i.e. nouns, adjectives and numerals) and pronouns change their cases. Nouns always appear in dictionaries in the nominative. There are six cases in Russian: Именительный падеж - Nominative case; Родительный падеж - Genitive case; Дательный падеж - Dative case; Винительный падеж - Accusative case; Творительный падеж - Instrumental case; Предложный падеж - Prepositional case; A small group of words (known as indeclinable) never change their form in any case - these tend to be words imported from other languages. They are кафе ( a cafe) - такси (a taxi) - радио ( a radio) - кино (a movie) - пальто ( a coat). Prepositional Case Denoting Place. To denote place not only adverbs can be used (e.g. здесь - here, там - there), but also nouns in the prepositional case with the preposition в or на. Most Russian verbs require a certain case, and the prepositional is used to indicate place after the following verbs: г д е ? (Where?) работать – to work; учиться – to study; жить – to live; сидеть – to sit ; cтоять – to stand; лежать – to lie; отдыхать – to rest. Prepositional Case for the Object Thought of or Spoken about. To denote the object thought of or spoken about, the prepositional is preceded by the preposition о. This preposition takes the form об when it precedes a noun beginning with a vowel. In such cases the noun answers the question о ком? о чём? Remember! The forms of the prepositional of personal pronouns: Nominative case - я( I)- ты (you)- он (he)-она (she)- мы(we) - вы (you)-они (they) Prepositional case - обо мне (about me)-о тебе (about you) - о нём (about him) - о ней(about her)- о нас(about us) - о вас (about you) - о них (about them).
