Declension - Skloňování¶
Introduction¶
There are several approaches to presenting the reality of Czech declension, categorising words, and visualising them for learning purposes.
Various sources, both originally Czech and foreign, use different model words to represent groups that other words belong to. By doing so, they demonstrate that learning one group's declension enables a student to correctly use other words in the same group.
However, there are some challenges, such as irregular declension, consonant alternation, vowel shortening, mixed declension, and differences between formal and spoken language, which make visualising the declension system difficult to present.
Declension, generally speaking, is a system of morphemes (endings) that express internal relationships between words when we combine them to refer to the reality around us. Czech, as an inflected 1 language, uses endings to denote grammatical, syntactic, and semantic features. Simply put, a word exists in several forms, and each form has its own specific meaning and usage. This is mainly, though not exclusively, because inflected languages do not have a strict word order. 2
Words that undergo changes in their endings are called inflectional (ohebná slova). The parts of speech that undergo declension are:
Cases - Pády¶
To express relationships between words, the Czech language uses a system of seven cases. These cases are named using Latin terms (a principle used in linguistics worldwide) or numbered (a system used in Czech schools).
For the purposes of this guide, we use Latin terms (the following table is sortable):
| Scientific term | Czech scientific term | Abbreviation used in this guide 4 | Traditional Czech numbering | Question word |
|---|---|---|---|---|
| nominative | nominativ | NOM | 1. pád 3 | kdo, co |
| genitive | genitiv | GEN | 2. pád | koho, čeho |
| dative | dativ | DAT | 3. pád | komu, čemu |
| accusative | akuzativ | ACC | 4. pád | koho, co |
| vocative | vokativ | VOC | 5. pád | - |
| locative | lokál | LOC | 6. pád | kom, čem |
| instrumental | instrumentál | INS | 7. pád | kým, čím |
Question words are traditionally used in the Czech school system. In fact, they are the declensions of the interrogative pronouns kdo and co.
Seven Peters Example¶
The following example shows how one word (Petr) is changed in different cases.
Petře, věděl jsi, že Petr šel k Petrovi a viděl Petra, který byl u Petra s Petrem a mluvili o Petrovi?
Peter, did you know that Peter went to Peter's place and saw Peter, who was at Peter's with Peter, and they talked about Peter?
Case analysis:
(VOC)Petře , věděl jsi, že (NOM)Petr šel k (DAT)Petrovi a viděl (ACC)Petra, který byl u (GEN)Petra
s (INS)Petrem a mluvili o (LOC)Petrovi?
Syntactic analysis:
(ADRESSEE)Petře, věděl jsi, že (SUBJECT)Petr šel k (PLACE-DIRECTION)Petrovi a viděl (DIRECT-OBJECT)Petra, který byl u (PLACE-LOCATION)Petra s (OBJECT)Petrem a mluvili o (OBJECT)Petrovi.
Agreement¶
Words that create a logical cluster (such as attributes and modifiers) have to agree in the case.
-
(NOM)[Ten náš nový dům] je krásný.
[Our new house] is beautiful. (lit. [That our new house] is beautiful.) -
Do (GEN)[toho našeho nového domu] jsem se přestěhoval před dvěma roky.
I moved into [(that) our new house] two years ago. -
V (LOC)[tom našem novém domě] bydlím už dva roky.
I have been living in [(that) our new house] for two years.
Cases and their typical usage¶
Nominative¶
The nominative case (from Latin nomen - name) denotes the subject of a sentence. It is the lemma (dictionary form), so when working with a dictionary, this form always appears first.
(NOM)Petr studoval.
Petr studied.
The nominative is also used for:
-
the noun (nominal) phrase after být (to be):
(NOM)Petr je (NOM)[můj kamarád].
Petr is my friend. -
the adjective phrase after být (to be):
Petr je (NOM)starý.
Petr is old.
Genitive¶
The genitive case (from Latin genus - race, kind, birth) is used:
-
after various prepositions (see Genitive prepositions for a detailed overview):
Včera jsem šel do (GEN)školy.
I went to school yesterday. -
after certain verbs:
Bojím se (GEN)bratra.
I am afraid of my brother.
Ptám se (GEN)učitele.
I am asking the teacher.

Cases and parts of sentence¶
With some level of simplification, we can say that
-
The subject is in the nominative case.
-
The direct object is in the accusative case
-
The indirect object is in the dative case.
(SUB NOM)Petr koupil (iOB DAT)Martinovi (dOB ACC)knihu.
(SUB)Peter bought a (dOB)book for (iOB)Martin.

Cases and prepositions¶
Grammatically, prepositions are very strong elements as they determine the case of the following word(s). From this perspective, Czech cases can be prepositional, non-prepositional, or both.0
| Case | Prepositional | Non-prepositional |
|---|---|---|
| NOM | ||
| GEN | ||
| DAT | ||
| ACC | ||
| VOC | ||
| LOC | ||
| INS |
More details
We can postulate the following:
-
NOM and VOC are non-prepositional cases only.
-
LOC is a prepositional case only.
-
GEN, DAT, ACC, and INS can be both prepositional and non-prepositional, with the use of a preposition historically determined by the verb.
-
The term fusional is also sometimes used. ↩
-
However, word order is not completely chaotic—the S-V-O (subject-verb-object) structure is commonly used. Visit the Word order page to learn more about the second-position rule and emphasised-position rule. ↩
-
An ordinal number is used, therefore 1. pád is pronounced as první pád, 2. pád as druhý pád etc. Check out page about ordinal numerals. ↩
