Adjective Agreement in Czech

In Brief

Czech adjectives change their endings to match the nouns they describe in gender, number, and case: velký dům “a big house,” velká žena “a big woman,” and velké dítě “a big child.” At first, learn the basic singular endings -ý, -á, -é and the nominative plural forms; later, extend the same agreement principle across all seven Czech cases.

Overview

An adjective is a describing word such as “big,” “new,” or “friendly.” A noun names a person, place, thing, or idea. English adjectives normally keep one form: “a big house,” “a big woman,” and “big children” all use big. Czech instead marks the connection between adjective and noun through matching endings. This matching is called agreement.

Three features control the adjective ending. Gender classifies a singular noun as masculine, feminine, or neuter. Number tells you whether the noun is singular or plural. Case is the form that shows what job a noun phrase does in a sentence—for example, who performs an action, what receives it, or what follows a preposition. The adjective and noun must carry compatible gender, number, and case forms.

Adjective agreement begins at A1 because it appears in even the simplest descriptions: nové auto “a new car,” dobrá káva “good coffee,” and český film “a Czech film.” The beginner rule is manageable: identify the noun’s gender and attach the matching basic ending. Czech case endings add more forms later, but they do not replace that rule; they apply it more fully.

How It Works

The beginner pattern: nominative singular

The nominative is the basic dictionary case. It commonly identifies the subject—the person or thing that performs the action—or a noun being identified after být “to be.” Most common adjectives follow the “hard” pattern represented by mladý “young.” Dictionaries list these adjectives in the masculine singular nominative form, usually ending in -ý.

Gender	Adjective ending	Example	Meaning
Masculine	-ý	velký dům	a big house
Feminine	-á	velká žena	a big woman
Neuter	-é	velké dítě	a big child

The adjective follows the noun’s grammatical gender, which is not always based on real-world sex. Dům “house” is masculine, kniha “book” is feminine, and město “city” is neuter, so Czech has nový dům, nová kniha, and nové město.

The same agreement appears when the adjective comes after být:

• Dům je velký. — The house is big.
• Kniha je nová. — The book is new.
• Město je krásné. — The city is beautiful.

The noun may not be repeated, but the ending still reflects it: Ta kniha je nová “That book is new.”

Nominative plural

In the plural, Czech makes an important distinction between masculine animate nouns—male people and many animals—and other nouns.

Noun group	Hard-adjective ending	Example	Meaning
Masculine animate	-í	mladí muži	young men
Masculine inanimate	-é	nové domy	new houses
Feminine	-é	dobré knihy	good books
Neuter	-á	malá města	small cities

With masculine animate plural -í, the final consonant may change. Common examples include velký → velcí, dobrý → dobří, and český → čeští. These spelling changes belong to the regular sound pattern of Czech, but it is useful to learn frequent forms as complete pairs.

Do not transfer the neuter singular ending to the plural: malé město is one small city, while malá města means small cities.

Hard and soft adjectives

Czech has two main adjective patterns.

1. Hard adjectives usually have masculine dictionary forms in -ý: nový “new,” dobrý “good,” malý “small.” They show the familiar nominative singular contrast nový, nová, nové.
2. Soft adjectives end in -í: jarní “spring,” moderní “modern,” cizí “foreign.” In the nominative, -í stays the same across all genders and both numbers: jarní den, jarní noc, jarní ráno, jarní dny.

An unchanged soft adjective is still agreeing with its noun. Its pattern simply uses the same visible nominative ending in several slots. Other cases reveal different endings, such as bez jarního kabátu “without a spring coat” and v jarním počasí “in spring weather.”

Agreement across the cases

Czech has seven cases. Once a noun phrase changes case, every adjective attached to that noun changes with it. Compare the masculine phrase nový dům:

Case	Plain-English function	Czech phrase	Meaning
Nominative	basic form; often the subject	nový dům	a new house
Genitive	often “of”; after certain prepositions	bez nového domu	without a new house
Dative	often “to/for” someone or something	k novému domu	toward the new house
Accusative	often the direct object	vidím nový dům	I see a new house
Vocative	direct address	uncommon with dům	—
Locative	used after certain prepositions	v novém domě	in the new house
Instrumental	often “with/by means of”	před novým domem	in front of the new house

A direct object is the person or thing directly affected by the action. In Vidím nový dům, the new house is what is seen, so it is accusative. Prepositions often require a particular case, which then determines both noun and adjective endings.

Here is the full hard-adjective pattern using mladý “young.” In the masculine accusative singular, animate means a person or animal, while inanimate means a thing or abstract idea.

Case	Masculine singular	Feminine singular	Neuter singular
Nominative	mladý	mladá	mladé
Genitive	mladého	mladé	mladého
Dative	mladému	mladé	mladému
Accusative	mladého (animate), mladý (inanimate)	mladou	mladé
Vocative	mladý	mladá	mladé
Locative	mladém	mladé	mladém
Instrumental	mladým	mladou	mladým

Plural endings are more unified. The nominative preserves the gender distinctions shown earlier; most other plural case endings are shared.

Case	Masculine animate	Masculine inanimate / feminine	Neuter
Nominative	mladí	mladé	mladá
Genitive	mladých	mladých	mladých
Dative	mladým	mladým	mladým
Accusative	mladé	mladé	mladá
Vocative	mladí	mladé	mladá
Locative	mladých	mladých	mladých
Instrumental	mladými	mladými	mladými

For soft adjectives such as jarní, keep -í throughout the nominative and accusative forms. The main additional endings are masculine/neuter singular -ího, -ímu, -ím and plural -ích, -ím, -ími. You do not need to memorize the complete case system before making basic descriptions, but you should always learn an adjective together with the case pattern currently being studied.

Adjective position

The neutral order is adjective before noun: dobrá restaurace, červené víno, starý přítel. An adjective can also be part of the predicate—the information stated about the subject—after a linking verb such as být: Restaurace je dobrá. In both positions, agreement is required.

Putting an adjective after the noun can add emphasis, contrast, or a classificatory/literary flavor, but it does not make the adjective invariable: káva černá still uses feminine černá. For everyday beginner Czech, adjective + noun is the safest neutral order.

Common Mistakes

Using the dictionary form for every noun

• Wrong: velký žena
• Right: velká žena
• Why: Žena is feminine, so a hard adjective needs feminine singular -á in the nominative.

Copying English and leaving the adjective unchanged

• Wrong: Mluvím s nový kolegyní.
• Right: Mluvím s novou kolegyní.
• Why: English “new” does not change, but Czech s “with” requires the instrumental case. Both the adjective and noun must show that case.

Treating every masculine plural alike

• Wrong: velké muži
• Right: velcí muži
• Why: A masculine animate noun takes the nominative plural adjective ending -í, often with a consonant change. Masculine inanimate nouns take -é: velké domy.

Using neuter singular -é for neuter plurals

• Wrong: malé města
• Right: malá města
• Why: Hard adjectives use -é with one neuter noun but -á with neuter nouns in the nominative or accusative plural.

Matching the nearest word instead of the noun being described

• Wrong: To město je velká.
• Right: To město je velké.
• Why: The predicate adjective describes neuter město, so it must be neuter even though no noun immediately follows it.

Making an adverb agree like an adjective

• Wrong: Dům je velmé velký.
• Right: Dům je velmi velký.
• Why: An adverb describes a verb, adjective, or whole situation rather than a noun. Velmi “very” has no agreement ending; only velký agrees with dům.

Usage Notes

Czech often uses adjectives where English uses a noun as a modifier. English can say “spring weather,” using the noun “spring” before another noun; Czech normally uses the adjective jarní: jarní počasí. Likewise, česká restaurace means “a Czech restaurant.” Treat these as genuine adjectives and make them agree.

Nationality adjectives and many other descriptive adjectives are normally lowercase in Czech: český film, anglická kniha. This differs from English capitalization. A capital letter may still be required at the beginning of a sentence or as part of an official name.

Several adjectives can describe one noun, and every one agrees: nová česká restaurace “a new Czech restaurant,” s novou českou restaurací “with a new Czech restaurant.” Coordinated adjectives do the same: Dům je starý, ale krásný “The house is old but beautiful.”

Beyond the Basics: Advanced Use

You do not need to master the following patterns at A1, but they explain forms you will meet later.

Masculine animacy matters beyond the nominative

In the masculine singular accusative, animate adjectives look like the genitive, while inanimate adjectives look like the nominative:

• Vidím nového studenta. — I see a new student. (animate)
• Vidím nový telefon. — I see a new phone. (inanimate)

This distinction affects nouns, pronouns, and numerals as well as adjectives. It is therefore worth learning whether a masculine noun behaves as animate or inanimate.

Possessive adjectives have their own pattern

Forms such as otcův “father’s” and matčin “mother’s” are possessive adjectives: they identify an individual possessor. They agree with the possessed item, not with the possessor. Compare otcův dům “father’s house,” otcova kniha “father’s book,” and otcovo auto “father’s car.” Their declension mixes adjective-like and noun-like endings, so it is best learned as a separate pattern.

Short adjective forms survive in limited uses

Some adjectives have short, mainly predicative forms: rád/ráda/rádo “glad; liking to,” zdráv/zdráva/zdrávo “healthy,” and hotov/hotova/hotovo “finished/ready.” They agree too: Jsem rád is said by a male speaker, while Jsem ráda is said by a female speaker. Many short forms sound formal, literary, or fixed; the long forms are more general. The highly frequent rád/ráda deserves separate attention because Czech uses it to express liking an activity.

Mixed-gender groups use masculine animate agreement

A group containing at least one male person traditionally triggers masculine animate plural agreement: Petr a Jana byli unavení “Petr and Jana were tired.” An all-female group uses unavené. In the past tense, the verb form also reflects this agreement, so the distinction appears beyond adjectives.

Meaning can interact with adjective position

The usual adjective-before-noun order is unmarked. Post-nominal placement occurs in terminology, official names, contrast, set expressions, and literary style. Sometimes the position helps distinguish a category from a temporary description, but there is no single English-style rule that predicts every case. Learn established names as complete phrases and keep ordinary descriptions before the noun.

Practice Tips

1. Build three-form sets. For each new hard adjective, say it with one familiar noun of each gender: nový dům, nová kniha, nové auto. Then add the four nominative plural groups.
2. Change whole phrases, not isolated endings. Take nová restaurace through short frames such as bez nové restaurace, k nové restauraci, and s novou restaurací. This trains adjective and noun as one unit.
3. Mark gender and animacy in your vocabulary notes. Write ten nový dům, ta nová kniha, to nové město, and label masculine nouns as animate when relevant. The demonstratives ten, ta, to make the agreement pattern easier to hear and remember.
