Possessive Pronouns in Czech

Overview

Czech possessive pronouns express ownership and agree with the noun they modify in gender, number, and case -- similar to adjectives. The first and second person possessives (muj, tvuj, nas, vas) fully decline, while third person possessives (jeho, jeji, jejich) are indeclinable, making them simpler to use.

At the A1 level, knowing the basic nominative forms of possessive pronouns allows you to talk about family, belongings, and daily life. The key challenge is that the possessive agrees with the possessed noun, not with the possessor -- muj dum (my house, masculine) vs. moje kniha (my book, feminine), regardless of whether the speaker is male or female.

This topic builds directly on adjective agreement, as possessive pronouns follow nearly identical declension patterns.

How It Works

Nominative Forms

Possessor	Masculine	Feminine	Neuter	Plural
ja (my)	muj	moje/ma	moje/me	moje/me
ty (your)	tvuj	tvoje/tva	tvoje/tve	tvoje/tve
on (his)	jeho	jeho	jeho	jeho
ona (her)	jeji	jeji	jeji	jeji
my (our)	nas	nase	nase	nase
vy (your)	vas	vase	vase	vase
oni (their)	jejich	jejich	jejich	jejich

Declension of 1st/2nd Person Possessives

Muj declines like a hard adjective with some special forms:

Case	Masc.	Fem.	Neuter
Nom.	muj	moje	moje
Gen.	meho	me	meho
Dat.	memu	me	memu
Acc.	meho/muj	mou/moji	moje

Third Person: No Declension

Jeho (his), jeji (her), and jejich (their) never change form regardless of the case, gender, or number of the noun they modify.

Common Mistakes

Agreeing with the Possessor Instead of the Noun

• Wrong: muj kniha (using masculine form because speaker is male)
• Right: moje kniha (feminine because kniha is feminine)
• Why: The possessive agrees with the possessed noun's gender, not the gender of the possessor.

Trying to Decline Jeho/Jeji/Jejich

• Wrong: jejiho domu (trying to decline jeji)
• Right: jejiho domu is actually correct for jeji in genitive -- jeji does have limited declension
• Why: Jeho and jejich truly never decline. Jeji has optional declined forms in formal Czech, but the base form is always acceptable.

Confusing Svuj with Personal Possessives

• Wrong: On videl jeho auto. (meaning his own car)
• Right: On videl sve auto.
• Why: When the possessor is the subject of the sentence, Czech uses the reflexive possessive svuj instead of jeho/jeji. This prevents ambiguity.

Usage Notes

The reflexive possessive svuj/svoje is used when the possessor is the subject of the clause. This is a B1 topic in full detail, but even at A1, awareness helps avoid a common error: Mam rad svou praci (I like my work) is more natural than Mam rad mou praci.

Practice Tips

1. Noun-possessive pairing: Take nouns of different genders and practice attaching possessives: muj pes, moje kocka, moje auto.
2. Family vocabulary: Possessives naturally pair with family words: muj bratr, moje sestra, nase rodina.
3. Third person contrast: Practice distinguishing jeho/jeji/jejich in sentences about other people.
