Declining Czech Place Names

In English a place name is a fixed label: you say Prague whether you live in Prague, travel to Prague, or talk about Prague. Czech treats town and region names like any other noun — they have a gender, they belong to a declension pattern, and they change their ending depending on the case. "I live in Prague," "I'm going to Prague," and "the centre of Prague" each require a different form of Praha. This page sorts the names by gender and pattern so you can decline any Czech toponym you meet. Its companion page on the locative of place names focuses on the single most frequent need — answering where? — while this page gives you the full case picture.

Place names have a gender

The first thing to recognise about a Czech place name is its gender, because that determines which paradigm it follows. You read the gender straight off the ending, exactly as you do with common nouns.

• Names ending in -a are feminine: Praha, Ostrava, Jihlava. A few feminine names end in a soft consonant instead, like Plzeň and Olomouc.
• Names ending in a hard or neutral consonant are masculine inanimate: Tábor, Beroun, Liberec, Kolín, Hradec, Mělník.
• Singular names ending in -o are neuter: Brno, Kladno, Znojmo.
• A whole class of names is grammatically plural (Pardubice, České Budějovice, Krkonoše); these get their own section below.

Feminine cities: the Praha type

Most feminine city names end in -a and follow the žena pattern. The catch English speakers always trip on is the consonant change in the dative and locative singular, where the stem-final consonant softens before the ending -e/-ě.

In Praha, the h softens to z: do Prahy (genitive, "from Prague") but v Praze (locative, "in Prague"). This is the same alternation you see in any žena noun whose stem ends in h, ch, k, g, r — see the feminine žena declension.

Some feminine names end in a soft consonant rather than -a, like Plzeň (Pilsen). These follow the píseň pattern: genitive Plzně, locative v Plzni. Notice the fleeting -e- drops out (Plzeň → Plzně) and the locative takes -i, not -e.

Masculine towns: the hrad type

Place names ending in a consonant are masculine inanimate and decline like hrad. The accusative is identical to the nominative (inanimate nouns don't mark the accusative), but the genitive takes -a and the locative usually takes -e/-ě with the familiar softening.

Watch the locative softening: Tábor → v Táboře (r → ř), Beroun → v Berouně (n → ně). One important sub-type is names ending in -ec, like Liberec. The -e- is fleeting, so it disappears whenever an ending is added, leaving a stem ending in the soft consonant c. That soft stem then takes soft endings — genitive -e, locative -i — so there is no further consonant change: do Liberce (genitive), v Liberci (locative).

Neuter towns: the město type

Names ending in -o are neuter and decline like město. The genitive takes -a, and the locative again softens the stem before -ě/-e.

Notice that Kladno takes na rather than v in the locative — na Kladně. This is lexical and unpredictable: a handful of towns historically take na, and you simply have to learn them. The companion page on the locative of place names covers the v / na split in detail.

Plural-only place names

This is the class that catches everyone, because the name looks singular in English but is grammatically plural in Czech. Towns like Pardubice, České Budějovice, Teplice, and mountain ranges like Krkonoše (the Giant Mountains) exist only in the plural. They take plural endings in every case — there is no singular form at all.

The genitive is the form English speakers least expect: do Pardubic ("to Pardubice"), with a bare stem and no ending. And the locative is v Pardubicích — never v Pardubice.

Two-part names: Hradec Králové

Some names have two parts, and you have to ask whether both parts decline. The honest answer is: it depends, and there is no single rule.

In Hradec Králové, only the first part declines. Hradec is a masculine -ec noun (like Liberec), so it gives do Hradce Králové, v Hradci Králové. The second part, Králové, is a frozen old genitive ("of the queen") and never changes.

In České Budějovice, by contrast, both parts decline, because České is an ordinary adjective and Budějovice is a plural-only noun: do Českých Budějovic, v Českých Budějovicích. The adjective agrees with the plural noun throughout.

Regions take na

Region names behave like ordinary nouns too, but several large regions take the preposition na rather than v, the same way English uses "on" for some islands and "in" for countries. Morava (Moravia) is the headline case: na Moravě ("in Moravia"), not v Moravě. The stem Morav- takes the feminine locative -ě and the v stays hard.

Note v Čechách ("in Bohemia") — Čechy is itself a plural-only name, hence the plural locative -ách.

Common mistakes

The single biggest error is the English habit of leaving the name unchanged after a preposition.

Forgetting the consonant softening in the locative is the next most common slip.

Treating a plural-only name as if it were singular produces an impossible form.

Finally, guessing v when the name actually takes na:

Key takeaways

• Read the gender off the ending, then decline with žena (-a), píseň (soft-consonant feminine), hrad (masculine consonant), or město (-o).
• The locative singular softens the stem: Praha → v Praze, Brno → v Brně, Tábor → v Táboře.
• Plural-only names (Pardubice, České Budějovice, Krkonoše) take plural endings everywhere: do Pardubic, v Pardubicích.
• A few towns and regions take na instead of v (na Kladně, na Moravě) — memorise these.
