Russian/Personal Pronouns

The personal pronouns in Russian are arguably the easiest to learn. As they do not modify nouns (unlike their possessive counterparts), they conjugate only by case. They are:

English First person Second person Third person
I / me We / us Thou
(sing. informal)
(pl. formal)
He / his It She / her They / them
Nominative Я Мы Ты Вы Он Оно Она Они
Genitive Меня Нас Тебя Вас Его Её Их
Dative Мне Нам Тебе Вам Ему Ей Им
Accusative Меня Нас Тебя Вас Его Её Их
Instrumental Мной Нами Тобой Вами Им Ей/Ею Ими
Prepositional Мне Нас Тебе Вас Нём Ней Них

There are two important nuances to these pronouns. First, notice that the masculine and neuter third-person singular pronouns are the same in all cases but the nominative, and in the genitive and accusative are pronounced 'ye-vo', not 'ye-go'. Second, if the pronoun's case is called by a preposition, third-person pronouns gain the prefix н- (e.g., compare 'his' in 'It's his house', Это его дом, and 'He has a house', У него есть дом).

Nominative: Where are you? - Где вы?
Genitive: What do you have there? - Что у вас там есть?
Dative: He's writing to thee - Он тебе пишет
Accusative: I love thee - Я тебя люблю
Instrumental: She's walking with them - Она с ними идёт - note the suffice н- after the preposition
Prepositional: We're talking about her - Мы о ней говорим
