Personal and Possessive Pronouns in All Cases

In this lesson, we will conquer one of the most essential topics in Russian grammar: Personal and Possessive Pronouns in all their forms. Mastering them is a huge step towards sounding natural and understanding spoken Russian. Let's dive in!

🔹 Part 1: Personal Pronouns (Личные местоимения)

Personal pronouns (I, you, he, she, it, we, they) change their form depending on their role in a sentence. This change is called declension, and the different forms are called cases.

Here are the basic forms in the Nominative case (who? what?):
я - I
ты - you (singular, informal)
он - he
она - she
оно - it
мы - we
вы - you (plural or formal)
они - they

Now let's see how they change in other cases.

➡️ Genitive Case (Кого? - of whom? / no one)
Used to show absence or possession.
▫️ меня (of me / no me)
▫️ тебя (of you / no you)
▫️ его (of him / no him)
▫️ её (of her / no her)
▫️ нас (of us / no us)
▫️ вас (of you / no you)
▫️ их (of them / no them)
Example: У меня есть книга. (I have a book - literally "By me there is a book")

❗️ The Magic 'н-' Rule
When a 3rd person pronoun (он, она, оно, они) comes after a preposition, it gets an 'н-' at the beginning.
▫️ для него (for him)
▫️ у неё (she has)
▫️ около них (near them)
This does NOT happen with 'меня', 'тебя', 'нами', etc.

➡️ Dative Case (Кому? - to whom?)
Used for the indirect object, the recipient of an action.
▫️ мне (to me)
▫️ тебе (to you)
▫️ ему (to him)
▫️ ей (to her)
▫️ нам (to us)
▫️ вам (to you)
▫️ им (to them)
Example: Он дал книгу мне. (He gave the book to me.)

➡️ Accusative Case (Кого? - whom?)
Used for the direct object of an action. For animate pronouns, the form is the same as the Genitive.
▫️ меня (me)
▫️ тебя (you)
▫️ его (him)
▫️ её (her)
▫️ нас (us)
▫️ вас (you)
▫️ их (them)
Example: Я вижу его. (I see him.)

➡️ Instrumental Case (Кем? - with whom? / by whom?)
Used to show the 'instrument' or a companion.
▫️ мной (with/by me)
▫️ тобой (with/by you)
▫️ им (with/by him)
▫️ ей (or ею) (with/by her)
▫️ нами (with/by us)
▫️ вами (with/by you)
▫️ ими (with/by them)
Example: Она гордится тобой. (She is proud of you.)

➡️ Prepositional Case (О ком? - about whom?)
Used ONLY with prepositions (like о/об - about, в - in, на - on).
▫️ обо мне (about me) - Note the 'обо'!
▫️ о тебе (about you)
▫️ о нём (about him)
▫️ о ней (about her)
▫️ о нас (about us)
▫️ о вас (about you)
▫️ о них (about them)
Example: Они говорят о нас. (They are talking about us.)

🔹 Part 2: Possessive Pronouns (Притяжательные местоимения)

Possessive pronouns (my, your, his, her, our, their) show ownership. They act like adjectives, so they must agree with the noun they describe in gender, number, and case.

These change forms:
▫️ мой / моя / моё / мои (my)
▫️ твой / твоя / твоё / твои (your, informal)
▫️ наш / наша / наше / наши (our)
▫️ ваш / ваша / ваше / ваши (your, formal/plural)

✅ These DO NOT change form:
▫️ его (his, its)
▫️ её (her)
▫️ их (their)
These are 'frozen' forms. Easy to remember!
Example: Я вижу его стол, его книгу, и его друзей. (I see his table, his book, and his friends.)

Declension example for мой (my):
Nom: мой брат, моя сестра
Gen: моего брата, моей сестры
Dat: моему брату, моей сестре
Acc: моего брата, мою сестру
Inst: моим братом, моей сестрой
Prep: о моём брате, о моей сестре

🔹 Part 3: The Super-Pronoun 'Свой'

Russian has a special reflexive possessive pronoun: свой (one's own).
It's used when the subject of the sentence is also the owner of the object. It can replace any other possessive pronoun in this situation. Using 'свой' is very common and sounds more natural.

It declines just like 'мой': свой / своя / своё / свои.

Compare these:
▪️ Я люблю мою семью. (I love my family.) -> Я люблю свою семью. (More natural)
▪️ Анна ищет свою сумку. (Anna is looking for her own bag.)
▪️ Анна ищет её сумку. (Anna is looking for her [another woman's] bag.)
▪️ Они взяли свои книги. (They took their own books.)
▪️ Они взяли их книги. (They took their [other people's] books.)

So, the rule is: if the owner is the subject, use свой.

That's a lot of information, but don't worry! Practice is key. Focus on understanding the tables and the logic behind 'свой', and you'll master pronouns in no time.
