Masculine Inanimate: The Hrad Paradigm | Czech Grammar

The hrad ("castle") paradigm is the hard masculine pattern for inanimate nouns — things, places, and abstractions whose stem ends in a hard or neutral consonant. It is the partner of the animate pán pattern, and the two look almost the same on paper. The decisive difference is the accusative, and it is driven entirely by animacy: a castle is a thing, so it behaves differently from a man.

This paradigm covers an enormous range of everyday words: dům (house), stůl (table), most (bridge), les (forest), vlak (train), byt (flat), strom (tree), obchod (shop), rok (year). If you can decline hrad, you can handle most of the concrete nouns you point at every day.

The full hrad paradigm

Here is hrad through all seven cases, singular and plural, with the question each case answers.

Case	Singular	Plural
Nominative (kdo? co?)	hrad	hrady
Genitive (koho? čeho?)	hradu	hradů
Dative (komu? čemu?)	hradu	hradům
Accusative (koho? co?)	hrad (= nominative)	hrady
Vocative (oslovení)	hrade	hrady
Locative (o kom? o čem?)	(na) hradě / hradu	(na) hradech
Instrumental (kým? čím?)	hradem	hrady

Look at the syncretism in the plural: nominative, accusative, vocative, and instrumental are all hrady. Four of the seven plural slots share one form, so the plural is far easier than it looks.

The inanimate accusative equals the nominative

Here is the rule that defines the whole pattern. When a hrad-type noun is the direct object, it does not change — the accusative is identical to the nominative.

Z dálky jsme uviděli hrad.

We caught sight of the castle from a distance. (hrad, accusative = nominative, unchanged)

Postavili nový most přes řeku.

They built a new bridge across the river. (most, unchanged as object)

Koupili jsme starý dům na vesnici.

We bought an old house in the village. (dům, unchanged as object)

Now set this beside the animate pán pattern, where the accusative takes -a:

Vidím hrad, ale ne pána, který tam má bydlet.

I see the castle, but not the lord who's supposed to live there. (hrad unchanged vs pán → pána)

💡

The accusative is the single test for masculine animacy. Vidím strom (a tree, unchanged → inanimate) but vidím psa (a dog, dog → psa → animate). If you ever forget whether a masculine noun is animate, ask: does its accusative add -a? That answer is its animacy.

The genitive singular: usually -u

The genitive singular of hard inanimate masculines is normally -u: od hradu (from the castle), do lesa... — and here is the first honest complication. A sizeable minority of these nouns take -a in the genitive singular instead: les → lesa (do lesa, into the forest), kostel → kostela, dvůr → dvora, chléb → chleba. There is no fully reliable rule; you learn the -a group word by word. But -u is the safe default for a noun you have not met before.

Bydlíme kousek od hradu, je to nádherný výhled.

We live a short way from the castle, it's a gorgeous view. (od + genitive: hrad → hradu)

Pojďme na procházku do lesa.

Let's go for a walk into the forest. (les → lesa, the -a genitive group)

The locative singular: -ě / -e versus -u

The locative singular has two endings, and choosing between them is the trickiest part of this paradigm.

Most hrad-type nouns take -ě/-e, which softens the consonant in front of it. The ending is spelled ě after d, t, n, b, p, v, m but plain e after s, z, l, r — same sound, different spelling:

Noun	Locative	Note
hrad	(na) hradě	spelled -ě after d
most	(na) mostě	spelled -ě after t
les	(v) lese	spelled -e after s
kostel	(v) kostele	spelled -e after l

But nouns whose stem ends in the velars k, g, h, ch — where -ě is impossible — take -u instead, as do most abstract and foreign nouns:

Ve vlaku nebylo jediné volné místo.

There wasn't a single free seat on the train. (vlak → vlaku, velar stem takes -u)

Na břehu rybníka seděl rybář.

A fisherman was sitting on the bank of the pond. (břeh → břehu, velar stem)

Na hradě byla spousta turistů.

There were loads of tourists at the castle. (hrad → hradě)

Vowel shortening: dům → domu

A handful of very common nouns shorten their root vowel in every form except the nominative and accusative singular. The model is dům (house): the long ů of dům becomes a short o throughout the rest of the paradigm — domu, domě, domem, domy — and then, neatly, the genitive plural brings back the long vowel as domů. The same shortening hits stůl → stolu (table) and vůz → vozu (cart, vehicle).

Bydlíme v novém domě hned za parkem.

We live in a new house right behind the park. (dům → domě, ů→o)

Na rohu stolu ležely klíče od domu.

The house keys were lying on the corner of the table. (stůl → stolu, dům → domu)

💡

Don't let the genitive singular domu and the genitive plural domů blur together — one short, one long. Bez domu = without a/the house (singular); spousta domů = loads of houses (plural). The length is the only thing telling them apart.

Common mistakes

❌ Vidím nového hrada.

Incorrect — hrad is inanimate, so the accusative equals the nominative; no -a is added.

✅ Vidím nový hrad.

I see a new castle. (hrad unchanged, adjective in inanimate accusative)

❌ Seděli jsme ve vlace.

Incorrect — a velar-stem noun takes the locative -u, not -ě.

✅ Seděli jsme ve vlaku.

We were sitting on the train. (vlak → vlaku)

❌ Vrátil se domů z lesu.

Incorrect — les is one of the -a genitive nouns: z lesa, not z lesu.

✅ Vrátil se domů z lesa.

He came home from the forest. (les → lesa)

❌ Bydlíme v starý dům.

Incorrect — the preposition v takes the locative, and dům shortens to domě.

✅ Bydlíme ve starém domě.

We live in an old house. (dům → domě, v → ve before the consonant cluster)

❌ Kolem jely tři vlaki.

Incorrect — the nominative plural of an inanimate masculine is -y, never the animate -i.

✅ Kolem jely tři vlaky.

Three trains went past. (vlak → vlaky)

The recurring trap for English speakers is importing the animate endings onto inanimate things — adding -a in the accusative, or -i in the plural — because English makes no such distinction. A castle, a train, and a table never take those endings.

Key takeaways

hrad is the model for hard masculine inanimate nouns: dům, stůl, most, les, vlak, byt, strom.
The accusative equals the nominative — the noun does not change: vidím hrad. This is the mirror image of animate pán (vidím pána).
Genitive singular is usually -u (hradu), but a fixed group takes -a (lesa, kostela, chleba) — learned word by word.
Locative singular splits: -ě/-e for most stems (hradě, mostě, lese), but -u after velars and for abstract/foreign nouns (vlaku, břehu). See the locative split for the full picture.
A few common nouns shorten their vowel: dům → domu/domě, stůl → stolu — but the genitive plural restores the long vowel (domů).
