Choosing dva versus dvě | Czech Grammar

English "two" never changes — two men, two women, two cities, all the same word. Czech splits it by gender: dva for masculine nouns, dvě for feminine and neuter ones. Because "two" is one of the most frequent words in the language, getting this wrong is conspicuous — a native ear catches dva ženy instantly. The good news is that the rule is short, it covers only a couple of numbers, and once you leave the nominative the whole distinction evaporates.

The core rule

Look at the gender of the noun and choose accordingly:

Noun gender	Form of "two"	Examples
masculine	dva	dva muži, dva domy, dva stromy
feminine	dvě	dvě ženy, dvě knihy, dvě sestry
neuter	dvě	dvě města, dvě okna, dvě auta

The split is two-against-one: masculine gets its own form (dva), while feminine and neuter share dvě. So the only question you ever ask is "is this noun masculine?" — if yes, dva; if no (feminine or neuter), dvě.

This masculine-versus-the-rest grouping is not random; it is a pattern you will meet again and again in Czech. Feminine and neuter constantly behave as one camp against masculine — in the plural of oba/obě, in many adjective and pronoun endings, in past-tense participles. Treating "feminine and neuter together" as a single mental box pays off well beyond this one word. And mind the pronunciation: dva is a plain "dva," but dvě has the soft ě, pronounced roughly "dvyeh" — the spelling and the sound both change.

Mám dva bratry a jednu sestru.

I have two brothers and one sister. (dva — masculine; jednu — feminine 'one')

Na stole leží dvě knihy a tužka.

There are two books and a pencil lying on the table. (dvě knihy — feminine)

V kuchyni jsou dvě okna.

There are two windows in the kitchen. (dvě okna — neuter, same form as feminine)

Koupil jsem dva lístky do divadla.

I bought two tickets to the theatre. (dva lístky — lístek is masculine inanimate)

Two and four take the nominative plural noun

Remember the counting agreement: two, three, and four are followed by the nominative plural of the noun (and a plural verb), exactly like counting any small quantity. So dva / dvě pair with plural nouns — dva muži, dvě ženy, dvě města — and never with the genitive that kicks in from five upward.

Bydlí tu dva muži a tři ženy.

Two men and three women live here. (dva muži — masculine plural; tři ženy)

Čekám tady už dvě hodiny.

I've been waiting here for two hours already. (dvě hodiny — hodina is feminine)

That last one connects to telling the time: you say dvě hodiny ("two o'clock / two hours") with the feminine dvě, because hodina is feminine.

tři and čtyři don't care about gender

Here is the relief. The gender split lives only in dva/dvě (and in oba/obě and jeden/jedna/jedno). From tři ("three") and čtyři ("four") onward, the numeral has a single form for all genders. So you sweat the gender on "two" and then stop worrying.

Mám tři bratry a čtyři sestřenice.

I have three brothers and four girl cousins. (tři, čtyři — identical for masculine and feminine)

💡

The whole gender headache is concentrated on the two most common numbers — dva/dvě and oba/obě — plus fully adjective-like jeden/jedna/jedno. Everything from tři up is gender-blind. So learn the "two" split well; the payoff is large and the rule then disappears.

oba / obě — "both" follows the same split

The word for both mirrors "two" precisely: oba for masculine, obě for feminine and neuter. If you know whether it's dva or dvě, you know whether it's oba or obě.

Oba moji rodiče jsou učitelé.

Both my parents are teachers. (oba — rodiče is masculine)

Obě sestry studují v Praze.

Both sisters study in Prague. (obě — feminine)

Obě města leží u stejné řeky.

Both towns lie on the same river. (obě města — neuter, same form as feminine)

(There is a dedicated page on both — oba/obě with its quirks, including the odd oboje.)

A peek at the declension

The gender split lives in the nominative and accusative. The moment you move into another case, dva and dvě both collapse into the same shapes — so the worry literally goes away:

Case	masc.	fem./neut.	"both"
nominative / accusative	dva	dvě	oba / obě
genitive / locative	dvou		obou
dative / instrumental	dvěma		oběma

Mluvil jsem se dvěma kamarády o tom problému.

I talked with two friends about that problem. (se dvěma — instrumental, gender-neutral)

Bez těch dvou klíčů se dovnitř nedostaneš.

Without those two keys you won't get inside. (dvou — genitive, same for all genders)

Note the instrumental is dvěma, never dvěmi — and "both" is oběma. Those two irregular shapes are worth memorising on their own; see the full declension of numerals.

Key takeaways

Masculine → dva (dva muži, dva domy); feminine or neuter → dvě (dvě ženy, dvě města).
oba / obě ("both") follows the identical split; jeden / jedna / jedno agrees fully like an adjective.
tři and čtyři (and every number above) ignore gender — one form fits all.
dva/dvě take the nominative plural noun (the 2–4 rule), e.g. dvě hodiny.
Outside the nominative/accusative the gender split vanishes: dvou (gen./loc.), dvěma (dat./instr.); for "both," obou and oběma.
